What if you, being here, could be a virtual presence anywhere?

MAS CAAD ETHz Theory Module 1 Dr. phil. Vera Bühlmann

A video of crowd behavior simulation in an existing context.

The agents have to pass from one checkpoint to another. In the course of that, they interact with each other and some interesting patterns emerge.

The algorithm was developed with object-e office, using python script in Real Flow.

object-e, August 2012

http://object-e.net/

This is an agent system based on Craig Raynolds' boids algorithm. My version is pretty simple, it only has the 3 rules and some boundary constrains. No fancy steering or viewing angle. Other than that, it includes some functions to send particle positions to Grasshopper and have them there as points.

other features are:

boid coloring is relevant to the amount of neighbors

pressing q draws lines to the current boid's neighbors

pressing < or > changes the current boid

selfish behavior - boids follow only others that are larger than them (toggles with S)

2D/3D mode (internal boolean)

and sending OSC to GH (toggles with O)

you'll need: peasycam, oscP5 and toxic libs (i provided the links in the processing file)

Here is a booklet (in Greek) and a video about my thesis project:

Open publication - Free publishing - More architecture

Finally! I presented my thesis project 3 weeks ago, and finished my studies (yay). My project was about designing a structure that could interact, move and adjust to the circumstances (there you go, trendy terms: interactive and kinetic). This was solved through programming; it couldn't otherwise be conventionally designed if you wouldn't wanted something that potentially moves, but something that you could make to actually move (CAD software does not support either the dimension of time or procedure design). So one part was trying to solve a structure that can do that, and the better part was coding; design the function-design for function.

So I began writing a program that would do that, and ended up with around 3000 lines of (processing) code. The hole bunch controls the movement/transformation of the structure; recognizes people in space (using the Kinect sensor) to interact with; sends data to a CAD program to draw the representational model (of its current state); and also outputs commands to Arduino for it to make some motors move.

To do this, I used a lot of stuff that a lot of very kind people opened to the web; firstly the Processing programming language and IDE, and the Arduino mircrocontroller; and some things, or better "tools", called libraries, such as toxic libs, peasy cam, simpleOpenNI, oscP5, blobDetection (I am sure I forgot something) and also other tools for Grasshopper called plug-ins, such as gHowl and Kangaroo physics. These I found in the internet and used for free, and if it wasn't for these people (the open source community in general) and the fact that they were for free, my project wouldn't be possible...

This is how things work and develop in this field. Some schizo produces the framework (ie Fry and Reas who made processing) and the thing grows and forks allover the place. What this essentially means, is that given that you have in your hands an object that is free, of which you are granted access to its plans (its source code), for some strange reason emerges a social trait of creative solidarity: offering your work back to the commons. Its strange because we rarely observe this behavior either in real life or other sides of the web social. If I may note an example from the architectural world: one can rarely find free rendering materials, created by a third party, to use in his/hers project; and we can agree that its not too difficult or time-consuming for someone with some degree of expertise to create a material.  On the other hand, the open-source culture is  you can easily find either tools (libraries) or examples of code for pretty much everything you can imagine... and also free of any charge. Visiting the fora for Arduino and Processing you should see people trying to help each other, solve each others programming problems and exchange chunks of code. Furthermore, if you ask a question in any of the open software/hardware based fora, I guarantee that you'll get quicker, more responses than any of the marketed software fora that are populated by users (even quicker than asking licensed software's support staff).

And the thing here, is that these people don't know each other in person, and probably will never meet. They could live in different countries, have different backgrounds, mother tongues, living standards, and belong to radically different social classes (and this is actually the case most of the time). In real life these people would never interact, even if they were not remotely positioned. But this is a by-product of the internet isn't it? Ok, yes internet brought us close. But the massive non-commercial collaboration between us was never envisioned before open-source hit the "general public". And this is the surplus value that comes along with open source. Take money out of the equation and we are all classmates.

The thing is not only that we (inherently) tend to help each other; help reach a common higher state of abilities (for example becoming all good programmers), this is only the the straight-forward value of OS. The other, what I call surplus, is the quality that describes assemblages; (among others) being more than the sum of its parts. An example: A population has an average IQ of 80; the highest IQ of the group is say 120. Helping each other (education maybe) strives to make everyone smarter, and rise the average to approach 120. Everyone being smarter means that everyone would be better on his/hers own, in his/hers own field; and everyone being better at what s/he does, means that everyone will produce stuff that would benefit the whole. This is primary linear interaction between the group and an individual: receive-return. Now is when things get kind of complex. I was saying how everyone can produce something that is great, but this is actually limiting, because this group -its parts- can produce stuff that can only reach "120-great". So if you start mixing qualities, mixing together everyone's knowledge you get the surplus. Nobody knows all the stuff on wikipedia, but if one counts everybody separately and do an addition, we certainly do; not only do we know wikipedia, we know hundreds of times more stuff. 

Eventually, it doesn't really matter how smart you are; if you contribute or not is what matters. Contributing to the whole for people to borrow, edit, improve and come up with different end products, is what makes the assemblage. The assemblage is more than the sum of its parts, because the assemblage does not have 120 IQ grade, it has 120 to the nth power... (somebody called Gilles said this first)

The open source community is an assemblage; its a creative avalanche. Being part of it raises its power to n+1. In the end, being part of it or not, at some point you will definitely benefit from it (don't you visit wikipedia? you are not obliged to contribute so as to be allowed to visit and read).

So similarly, in the process of working for my project, I did produce some stuff that could be useful to other people. If I gave them the material and (note) the permission to use/edit/republish (the basis of GPL-license), they could utilize it for projects they do in (probably vastly) different fields from mine. And so I did; I open-sourced 2 things so far: sending point arrays from processing to grasshopper, and some manipulation methods and infrared people tracking for the kinect sensor that can be found here and here. (i got some more things to leak when I find some time, such as an agent system; how to have more than one windows in P5 and a method to control stepper motors from processing without programming arduino).

Now, I have no idea if somebody is interested in my stuff, or if anybody has already used something of mine. I would be happy if someday somebody benefits from my work. I'd even be happier if somebody takes it and improves or enhances it (adds his/hers n+1) in the cause of his/hers project, because then I would know that a. what I did is usefull and b. I would be offered something that goes beyond what I was able to do or think.

This is how things work for open source. This is why they happen fast, and in every direction. Somebody makes a tool, somebody else takes it and uses it for something else. The creator, or the n=1, could never know the use that people after him/her will give to the tool; or better said: "the inventor doesn't know the invention". People will find the (multiple) use for the invention. 

Another example. Some years ago Nintendo made Wii (the game-platform with which you can play tennis holding a remote control in your hand). The main thing was its control, the wii-mote. This little thing has an infrared transmitter, bluetooth, accelerometers and gyroscopes, but because its massively produced it only costs something like 30 euros or so. Well, some people saw potential in this thing other than wiggling it around and playing virtual tennis (or whatever), and so they begun a process called reverse-engineering to try to (hardware) hack it and use it for something else. A lot of people worked for this and finally did it (http://wiibrew.org/wiki/Homebrew_Channel). They do offer what they did for free so it can be used by anybody to do anything. Now, the thing is that what they did is actually kind of illegal. The wii-mote is a proprietary hardware and can legally be used only as a tennis-whatever-remote-control for the games that Nintendo publishes for you. So the wii-mote as ingenious as it (really) is, is not a contribution, or a tool, its only a product restrained to consume Nintendo stuff (proprietary product and use too).

Unlike the wii-mote, the Microsoft Kinect followed a different path. So a couple of years back Microsoft made the Kinect for the Xbox 360 (another game console). This is an infrared/rgb camera that can see stuff/people in space. This means now that with Xbox, you can play tennis without holding anything! Fantastic! Regularly some people thought that it might do other (equally) useful stuff rather than tennis without remote, and got into the process of hacking it... Note that Kinect was some years after the wii so Microsoft knew its example. Some months after it was released, and it was known that some people were already disassembling it, Microsoft decided to release the source code (of the device data output) for people to be able to use it beyond their gaming console legally. Eventually Kinect is a contribution. When you buy it, you do buy the hardware without restrictions for its use. It now is a tool, and anybody can find a use for it (parallel to being presumably patented hardware). Furthermore, Microsoft did open a framework called XDK for people to develop legally their own software for Xbox too. And the thing really flourished. The projects that people conceive of and undertake are unimaginable.

The previous examples refer to tools, that can be taken and given use. They are usually developed in the course of larger projects, and are offered as autonomous objects, while the "larger project" the end product is not offered at all. This less than full-blown open sourcing.  Determined open source kind of people, do offer everything. A nice example for this is Lady Ada, a talented engineer who has released a ton of complete projects for free. Stuff like an mp3 player, an oscillator-synth, a led message thingy and many many more original and interesting projects. She is one of the leaders of what is called "The makers movement" and she made it to the Wired (mag) cover. But Lady Ada didn't actually made any money selling the stuff she designed, and actually is getting ripped off by some people who take her designs, mass produce and sell them. Though, she keeps doing what she does best. The questions are why does she continues doing this, and how does she actually survive. Well, there is a great lecture she gave justifying the why, which you can watch here. And how she survives? She owns a company called Adafruit that sells component kits for people to build the devices she designed. So she sells stuff like circuit boards, chips, microcontrollers, resistors and capacitors. You'd thing that she must be having a hard time but I will tell you she is not getting evicted any time soon. She earns money selling these building kits, which are offered for significantly less than the price of the end product. Both ends benefit; its a win-win. 

Now back to my project. As I said I designed a structure that can move, and wrote a program that controls it. The structure is a pyramidal space-frame surface consisting of hydraulic beams, that has a lot of capabilities to move between boundaries. My program computes the transformations and sends signals (pulses/PWM) to a distributor or motor (hydraulic compressor) which feeds the beams so that they change their length. I don't even know if this thing would work for real, I think it will, but I don't have the means to construct and test it. If I opened the source code to the web, somebody could download it, take a look at the program, improve it and build it. Pretty good.

Thought... I lean towards not doing so, and I'll tell you why. Say it actually works, its a big deal, and some people see some potential in it and want to build it. But my project is not a 40 $ mp3 player; it would cost some tens of thousands $ -or more- of pneumatic beams, compressors, sensors, metal joints, and probably additional professional programmer work. Somebody interested in building it would certainly not do so to benefit the whole, but to invest, to make money out of it. This purpose contradicts why I bothered working on the project in the first place...

The purpose I have for my project (besides some secondary performative applications) is kind of different, and has a social dimension. Its destined to be placed, as an installation, in public space; I specifically proposed to set it up in Omonia Square in Athens. My presumption is simple and it goes as follows: setting an object in public space, which has interactive capabilities, the ability to do something relatively to what people do, be actuated by them and provoke them too, would act as a catalyst for the social. This kind of blind object that only sees people (and not color, class, age or anything of that sort) offers back to them an equal capability to affect it, which is what -in my opinion- creates a social bond in space that didn't exist before. Regarding use, this this is kind of "useless" it doesn't do something, except from a collective morphogenesis maybe (which probably is not of much interest), but what is actually gained is the surplus social, produced in the process of interaction. Interaction between people and the structure, interaction among people themselves; unrelated people that would otherwise never gather together, take part in a collective process (form-finding or just play) that bonds them hopefully for more than the duration of the interaction. 

Why did I get in so much trouble to do this?

Because a funny thing that moves would work as a "particularity" for a place that does not have, or has a loose spacial character, and thus is not regarded by people as a "loci" in the city, but rather as a place that one has to pass from to get from A to B. This will probably attract people to come and stay for a while, not only because of the installation and what it does, but because the installation offers a character to that place that distinguishes and transforms it from generic to particular; that works as a landmark.

Furthermore, I believe -at least for my country- that the public has failed. It failed as space and as a common; it constantly loses ground in the battle with the private and the commercial. The fact is not only that a spacial quality disappears, but a general one; the sense of the whole, the commons, the public or general ownership of the public (which is different from state ownership). That being the case, I wanted to -artificially- try and bring back the sense of social in public space, among co-located and unrelated people that could reflect back on metropolitan life in general.

So that's why I think I will not open source my code. Because if its built it will be used in applications aiming profit; and the thing is not that I don't get my share, but that my work will get twisted as just another flavor of the week by somebody who won't even care who/what/why. 

I will certainly post some chunks that I consider useful, as well as my presentation (drawings, renderings etc) so stay tuned. However I am still thinking about opening the source code or not.

(or in simple terms, 3d blob tracking from kinect infrared sensor in processing)

Since the last time I had to enhance my kinect functions, to a large extend so as to have more options while programing for interaction. Some of these are record and playback, and blob detection. I could not find any examples of blob detection of Infrared data, and because I want to detect stuff in XYZ I couldn't use the RGB camera. So I wrote some functions to for that using an off screen buffer to draw points in plan, and feed that image to the blob detector.

The features include:

No significant FPS (processing speed) drop. With live kinect data feed, and also reading from file, and detecting blobs simultaneously for both feeds, I don't drop under 40-45 FPS (I also tested it in my larger project sketch, which runs some pretty heavy stuff, and I didn't have any drops there neither - on a quad core laptop).

Loading and closing kinect at anytime you want, as opposed to loading it at the beginning and have it on at all times. Moreover the sketch and the import functions CAN run with NO kinect connected to the PC (toggles pressing ENTER).

Transformation functions for adjusting the position of the sensor in processing with that of the real sensor in your installation (real transformations without matrices):

Rotate Sensor position in the XY plane (plan angle) (shift+right/left)

Rotate sensor position in the YZ plane (side view angle)(shift+up/down)

Move the position of the sensor in XY(arrow keys)

Move the position of the sensor along the Z axis (Page Up/Page Down)

Control of the scale of the kinect data

Optional saving of the transformed kinect points in a Vector array to access in other parts of the sketch (also for data imported from file)

Record/playback functions:

Record (raw) kinect input data in CSV file (HOME/END, start/end recording)

Import CSV file and playback recorded data in variable speeds with freedom on transformations (XY, YZ angles, scale and sensor position) (INSERT toggles playback, Shift+Space toggles its animation).

Blob functions:

Detect Blobs' X,Y coordinates  (I couldn't get their Z coordinate, I think its more complex but possible)

Save blobs in an array, and use them in other parts of the sketch

The libraries I used (the developers of which I would like to thank):

toxic libraries - http://toxiclibs.org/

simpleOpenNI - http://code.google.com/p/simple-openni/

BlobDetection - http://www.v3ga.net/processing/BlobDetection/

Peasy camera - http://mrfeinberg.com/peasycam/

Download p5 source here (broken link fixed)

notes:

to use Recording and Importing functions, HOME/END-INS you have to edit the csv path string from the sketch, otherwise you'll get a null pointer crash. I have written some comments in the sketch regarding what you have to write there.

I did add some lines of code for the buffer drawing, trying to optimize blob detection. The first thing is to compensate for the loss in pixel density for object far from the sensor and the second to try to cancel out stuff like walls for the blob detection. They need some more work to be done. I'll do a field test some time and improve it.  If these things don't work for you just comment out that part.

I also added an approximate boundary box for the kinect depth data.

I am currently trying to wrap up my diploma project, and as part of a larger sketch I am developing, I wrote some functions that manipulate the position of the Kinect sensor input in the processing sketch.The point is to avoid matrices, so as to have the kinect points, in proper cartesian relationships with the rest of the stuff in the sketch besides kinect input.

The sensor manipulations that can be controlled are:

position of the sensor on the XYZ plane

rotation of the sensor about the Z axis (plan angle)

rotation of the sensor about the X axis (side view angle)

it also includes an extensive documentation on what it does. My method is based on simpleOpenNI examples, and I use the toxic libraries vectors, and peasy cam. Links for download are in the sketch comments.

have fun and share alike

a short review for imdb:

Although a Cypriot myself, I have to admit that Cyprus has not accustomed us to good productions (I mean cypriot productions, although directors from Cyprus have risen to fame mostly through Greece). Fortunately this is an exception.

It deals with Andy-Andreas, a Cypriot raised in London, living with his dementia-suffering mother, German girlfriend and her daughter, working in a fish and chips restaurant. He decides to go back to his apparent homeland, for his mother to rest, and for him to make a fresh start. Welcomed by his brother, who migrated back some years before him, to his "noble" house and lifestyle, where he's trying to open a fish restaurant. Upon arrival all seems promising, until you cross the backdrop and it all falls apart.

The movie is not just a straightforward drama. It's a harsh criticism with a good deal of irony regarding the vanity and fragility of the modern Cypriot culture. Rich on mortgage; cars, brands and pool mansions for social status; a noble traditional hospitality that can be turned upside down by losing control of the otherwise controlled -politically correct- environment of the child; a suffering mother that distresses a perfect yuppie lifestyle; xenophobic prejudice; frail marriages based on well being only; and the list goes on. An idyllic postwar (1974-) life constructed on a basis of ethnic unity against a common enemy. And the twist of the film does not hold up. All has to be contradicted, all to be proved a lie, even lies told to oneself.

note: A taboo breaks. It's the first time I have seen cypriot talk subbed for greek audiences. 

note 2: The film crosses some unspoken boundaries for sure, its not politically correct in any dimension. Its provocative both cultural or national -wise. Although I've not heard from people in Cyprus that have seen the film, it would definitely be interesting to listen to their say.

Some months ago, with some colleagues of mine, I took part in a theoretical competition, that asked, more or less, to design an immoral utopia. Our entry was categorical, not to the immoral part, but to the utopian. We based that on a material ontological model we attempted to construct, and so the text and images we subjected did not show any utopia, but rather wanted to explain the emergence of morality.

After the competition finished I occasionally worked on the text, trying to complete its argument towards my personal point of view. Yesterday, Ι decided eventually that its kind of complete for now, and published it through academia.

You can read and download it from here: http://ntua.academia.edu/ConstantinosMiltiadis/Papers/1647746/The_folds_of_a-topia_or_a_materialist_take_on_Utopia_

note: It was nice to see that other entries, including the one of Joao and Raquel (link), two young Portuguese architects working in Athens, share the same intention (that of denial).

Here's a preview of the project I've been working on the past month. Its a spacegrid that consists of pneumatic elements, and thus, its able to deform and take different arrangements. Besides Processing, Rhino and Grasshopper, it makes use of  (and I would like to thank the creators of) gHowl, OscP5, Weaver Bird, Mesh Analysis and Kangaroo.

As of now the program is a platform for moving nodes manually. If I do continue the project, the goal is to make it in some way interactive/swarmy.

Processing and Grasshopper communicate via OSC (as in the definitions in my previous post), although I did encounter some problems when feeding multiple streams of data to GH. Also, as I set up things, Kangaroo has to reset most of the times, otherwise it makes a meshy mess.

The following is a method for real time communication between Processing and Grasshopper. Although there are some of methods for doing so (spreadsheets, udp etc) this one is kind of simpler and easier, and its actual latency is minimal. We tried to use the least code/libraries and plug-ins possible, to send a 2d point array from P5, and reconstruct it in GH. In the same manner, one can send multiple different streams of data programmed in P5, and visualize them in Rhino. The reason for this is that -at least for me- its easier to program a behavior in P5 in the same way that is easier to associate and render geometry in GH.

We used OscP5 library and the Osc components from gHowl plug-in.

Follow the explanation written in the processing sketch. The GH diagram is based on gHowl examples.

//thanks goes to my friend pk for his help

Το “περιμένοντας τον Γκοντό’ είναι το πιο γνωστό έργο του Ιρλανδού θεατρικού συγγραφέα Samuel Beckett, που ανέβηκε για πρώτη φορά το 1953. Από τότε έχει γίνει ένα από τα πιο δημοφιλή θεατρικά έργα, λαμβάνοντας διθυραμβικές κριτικές και πάμπολλες αναλύσεις.

Ο Μπέκετ, καταφέρνει να φτιάξει ένα έργο, που όπως έχει ειπωθεί αρκετές φορές, δεν συμβαίνει απολύτως τίποτα. Κανένα στοιχείο ή πράξη στο έργο δεν φαίνεται να έχει εμφανές νόημα, ούτε κάποια αξία. Ακόμα και η εμφάνιση των περαστικών δεν παίζει κανένα ρόλο στην εξέλιξη της πλοκής, αλλά περιορίζεται σε ένα αυτοαναφορικό γεγονός. Σε κυκλικές κινήσεις αυτοαναφοράς εκτυλίσσεται και το έργο, χωρίς να παρουσιάζεται κάποιος καταλύτης της πλοκής, παρά μόνο καταλύτες χρόνου, στο σκοπό της συνάντησης με τον Γκοντό, που τροφοδοτούν το γεγονός της αναμονής. Ελλείψει αναφοράς σε ένα παρελθόν, πραγματικό ή φανταστικό, με την προσδοκία μόνο μιας συνάντησης που διογκώνεται φαντασιωδώς σε σωτηρία, οι ήρωες βρίσκονται εγκλωβισμένοι σε ένα επίμηκες παρόν, είτε αμφισβητήσιμο είτε αόριστο, που φαίνεται να ταλαντώνεται στις δυο πράξεις του έργου. Μια διεσταλμένη ενδιάμεση στιγμή που παίζει και ξαναπαίζει, αναδιοργανώνοντας τυχόν εμβόλιμες λεπτομέρειες, γύρω από ένα σταθερό σημείο που παρουσιάζεται στο πρόσωπο του Vladimir· ο οποίος διατηρεί μια συνείδηση σε σχέση με το χρόνο ταυτόσημη με αυτή του θεατή.

Σαν ένα όνειρο που επαναλαμβάνεται, τακτοποιώντας πρόχειρα οποιοδήποτε άλλο συνειρμό προκύψει, διατηρώντας όμως σταθερό το τέλος και το σκοπό του. Δεν θα υπάρξει κάποια εξωτερική λογική εξήγηση των συμβάντων, παρά μόνο μια τακτοποιητική εσωτερική. Το παρελθόν, η ιστορία ή μια ευρύτερη διάσταση του χρόνου, υπό αυτές τις συνθήκες -του ονείρου- δεν παρουσιάζονται ποτέ, αποφεύγοντας να εκδηλωθούν ή να κάνουν αισθητή την παρουσία τους. Κάπου όμως υπάρχει το παρελθόν, έστω και ανεπαίσθητο, σαν ένας μικρός παρεμβατικός Θεός που φέρνει και ξαναφέρνει παρελθοντικά αντικείμενα ως θραύσματα, είτε επειδή κάτι θυμήθηκε, είτε επειδή δεν μπορεί να κάνει και αλλιώς, σε ένα παρόν που αφήνεται πλέον στο έλεος της λογικής, που επιδιώκει να δέσει πρόχειρα τα ξεβρασμένα αντικείμενα μεταξύ τους -να τους στερήσει μια άλογη αυτοτέλεια που δεν είναι από μόνη της άλογη γιατί απλά δεν ζητά εξήγηση αλλά αυτονομία- ανάγοντας ή μειώνοντάς τα σε δομημένους τρόπους που υπηρετούν σχεδόν προφανείς σκοπούς. Μια κανονικότητα στην οποία στήνεται ένα παράνομο κρυφτό, όπου τα ανεπιθύμητα εμφανίζονται, ενώ ο διαιτητής του παιχνιδιού τρέχει να τα συμμορφώσει, όπως όπως, με τους κανόνες.

Οι περαστικοί έρχονται και παρέρχονται, μπορούν να παρουσιάζονται κάθε μέρα με διαφορετικές συμβολικές παραστάσεις για να επισκιάσουν την προέλευση τους· μπορεί να είναι είτε τυφλοί είτε κουφοί, μπορούν να φέρουν διαφορετικά ονόματα ή εμφανίσεις. Θα περνούν όμως καθημερινά και ανελλιπώς, χωρίς η επίσκεψη τους να αφήνει εμφανή ίχνη, όντας φαινομενικά αδιάφορη, αλλά έχοντας βαθιές ρίζες σε κάποιο πραγματικό που επιστρέφει από το παρελθόν και επιδιώκει μέσα από ασυνάρτητες επενδύσεις, να προτείνει το δικό του δημιουργώντας αναταράξεις, χωρίς όμως να δίνει λόγους ή να υπάγεται σε γραμμικές ακολουθίες.

Αν και η διαδικασία εκλογίκευσης, μια επιπολαιότητα που προσπαθεί απλά να συμβαδίσει με τη συνεχή ροή στοιχείων που εναποτίθενται μπροστά σε κάποιου είδους διπολικά πλεκτή συνείδηση παραμένει εξωτερικά παράλογη προς μια πραγματικότητα στην οποία λαμβάνει μέρος μια διαφορετική μορφή λογικής, δεν είναι η τελευταία καθόλου ξένη με την προηγούμενη, αλλά μάλλον ταυτόσημη. Στερείται μόνο την αφόρητη ευτροφία ενός ασυνείδητου πλούσιου σε κτήματα τα οποία είχε μια ολόκληρη ζωή να εφοδιαστεί, συνιστώντας τελικά μια σκέψη περιθωριοποιημένη από την πληρέστερη νευρική διάταξη του εγκεφάλου, στην οποία διατίθενται μόνο τα απολύτως απαραίτητα, τα λογικά, αυτά που χρειάζεται να γνωρίζει για να λειτουργήσει, παρά όλα τα υπόλοιπα που ορίζουν τους τρόπους πρακτικής της λειτουργίας. Μια ελαττωμένη συνείδηση που είναι μόνο εξωτερικά λειτουργική.

Αυτή η δεύτερη τάξη σκέψης μπορεί πλέον να ρωτήσει “γιατί”· προηγουμένως δεν μπορούσε να κάνει αλλιώς παρά να λειτουργήσει αναδρομικά και υστερόβουλα, δίχως τέτοιες επικίνδυνες ερωτήσεις που το μόνο που θα πετύχαιναν ήταν να περιπλέξουν τα πράγματα φυτρώνοντας παντού αδιέξοδα και τερματίζοντας το παιχνίδι μέσω ακύρωσης της μιας από τις δυο αντίρροπες δυνάμεις. Μπορεί τώρα να διεργαστεί τα πεπραγμένα για να τα φέρει σε μια πιο πειθαρχημένη ακολουθία χωρίς ελεύθερες απολήξεις, υποβάλλοντας τα στην κρίση της. Τα τακτοποιεί και τα μετρά, περνώντας τα από το ίδιο νήμα, και πιθανολογεί για τις εκβάσεις τους. Παραγνωρίζει όμως ότι το “επειδή” είναι εφαπτόμενο στο “γιατί” απλά σε κάποια άπιαστη πλέον διάσταση. Αυτή η τάξη που καταλαμβάνει ενίοτε τον Vladimir, είτε σε διερωτήσεις που παράγει ο εαυτός του, είτε σε τάσεις παραίτησης που εκδηλώνει ο Estragon, αναλαμβάνοντας σε μια κατάσταση ξύπνιου σε ύπνωση να αιτιολογήσει τον εαυτό του στο παρόν.

Vladimir και Estragon, Pozzo και Lucky, δυο ασύμπτωτα ζεύγη αντίρροπων δυνάμεων, μη αντιμαχόμενων ούτε μεταξύ τους, ούτε ανά ζεύγος, αλλά ανταγωνιστικά, που συνιστούν δυο εγκάρσια επίπεδα, όπου το καθένα προσπαθώντας να προλάβει το άλλο περιστρέφονται από το κεντρομόλο εγώ· στην ένωση δυο μισών κρίκων της ίδιας αλυσίδας. Το πρώτο ζεύγος ριζωμένο στο παρελθόν και το δεύτερο κοιτώντας στο μέλλον, επιδιώκουν να αδράξουν και να συνδεθούν γραμμικά και αποκλειστικά με ένα αδιαίρετο παρόν, που αποτελεί το σημείο της εντατικής τους συσσωμάτωσης.

Το έργο μπορεί να είναι η αναπαράσταση μιας πολλαπλότητας, την οποία ο Μπέκετ τοποθετεί σε ξεχωριστά και ορισμένα σώματα, που δεν φτάνει να παράξει αντικείμενα, ούτε και τον εαυτό της. Εμμένοντας σε μια κατάσταση εναγώνιας μοιρολατρίας που υπερτερεί της φυγής, καταφέρνει να επιφέρει μια αδράνεια που αναδιπλώνεται στον εαυτό της ως στατική παύση, μακρυά από οποιοδήποτε ενεργητικό γεγονός. Ο μόνος καταλύτης στο έργο δεν είναι κάποιος πρωταγωνιστής, αλλά τελικά το παιδί, που εκ μέρους του Γκοντό απαλείφει τα πεπραγμένα και σηματοδοτεί ένα κομβικό σημείο στο ίχνος του χρόνου. Ο μόνος ρόλος του τετράπτυχου, αντίστοιχα, που δεν αναπτύσσεται είναι ο ίδιος ο Vladimir που εμφανίζεται σαν παράγοντας μιας ενεργητικότητας συρρικνωμένης, που μένει πάντα στα μισά και ακυρώνει τον κόμβο στο τέλος της ημέρας, χρησιμοποιόντας τον για να επιστρέψει στην αφετηρία και να ξαναμπεί στον τέλειο βρόγχο. Σαν μια εικονογράφηση της jouissance, ενός κωμικού εφιάλτη, μιας πλασματικά ευχάριστης κατάστασης, τροφοδοτούμενης από μια παθητική ελπίδα, που υφίσταται μόνο για να καλύψει μια βαθύτερη οδύνη και μια εδραιωμένη αμφιβολία.

the following sketch shows you how to make an etch-a-sketch type game on your pc with an arduino and a couple of potentiometers. this was my first arduino "project" i'll update it when i find some time.

Ingredients:

1 arduino of any kind/make with its USB cable

2 potentiometers

1 breadboard

some jumper cables

optionally an LED

I am using analog pins 0 and 1, and the COM4 usb port.

*i guess, if you want to advance this sketch you'll have to draw lines between points.

**if you are more advanced you can use the arduino P5 library. This way, uploading "standard firmata" on your arduino you can control it straight from processing. I'll probably try it and post the code some time

Process:

Arduino source:

int potL = 0;  int potR = 1; // the 2 potentiometers are connected to analog pins 0 and 1 void setup() {     Serial.begin(9600);   //initiate serial communication at 9600 b/r } void loop() {  int valR = analogRead(potR);  int valL = analogRead(potL);    Serial.print(valL );  Serial.print(',');  Serial.print(valR );  Serial.println(".");  delay(1);  

//this bunch prints: "leftValue,rightValue." every mSecond. these    //values get separated in p5 }  

P5 source:

import processing.serial.*;  //import serial library in p5 Serial potIn; float  vL,vR=0; int index,x,y=0; String raw=""; void setup() {   size(800,600);   background(0);   stroke(255);   potIn=new Serial(this,"COM4", 9600);

//com4 has to be altered according to your USB port that Arduino is //connected to  

potIn.bufferUntil('.');  //wait until dot } void draw() {  x=round(map(vR,0,1023,0,width));     y=round(map(vL,0,1023,0,height));

   //remap 8bit arduino values to display window size values   ellipse(x,y,3,3);         //draw a circle (etch dot) } void serialEvent(Serial potIn) {   raw=potIn.readStringUntil('.');   raw=raw.substring(0,raw.length()-1);

  //^remove the dot at the end  //of each transmission   index= raw.indexOf(",");  //find index of comma   vL=float(raw.substring(0,index)); //get value left of the comma   vR=float(raw.substring(index+1,raw.length())); //get value at right }
