Feedback Loops: How nature gets its rhythms by Anje-Margriet Neutel

While feedback loops are a bummer at band practice, they are essential in nature. What does nature’s feedback look like, and how does it build the resilience of our world? Anje-Margriet Neutel describes some common positive and negative feedback loops, examining how an ecosystem’s many loops come together to make its ‘trademark sound.’

Façades (2014) by Sabrina Ratté (a contribution for Broadway Augmented)

Videofeedback was used in trying to create aliens for Stanley Kubrick's film 2001: A Space Odyssey

"We spent an enormous amount of time trying to design extraterrestrials that we could include in the film. I produced quite a few alien effects using video feedback. Video feedback has a strange kind of lifelike quality to it, so I made a video feedback system for creating totally nonhumanoid shapes of pulsating light."

- Douglas Trumbull

Love Letter to Whatever (2014) by J. Robinson

A series of five analog feedback loops, performed live to tape on 1980's consumer video mixers, continuing my exploration into the materiality (color, texture, form) of video. Signals being pulled apart and reformed. And some cats too.

green piece / memory maze  by Anne Wellmer

green piece / memory maze is a composition by anne wellmer for viola, feedback, laptop and light. The piece explores the acoustic and architectural properties of a performance space, which undergoes a transformation through the enlarged micro-cosmos of the resonating viola strings and the site specific resonances excited by feedback. The title of the piece refers to Les Bains in Brussels, an out-of-use swimming pool building, where the piece was originally conceived.

edge case (2008) by Mike Hall Studio

Two projection feedback setups were positioned side by side, so that only their extreme edges were connected.

greyscape (2010) by Raymond Salvatore Harmond

Improvisationally generated circuit bent video feedback. Pass through analog to digital to analog. The signal is pushed into the audio filter then back out to the video, causing the desaturation of the video encoding (with the exception of a few short bursts of color noise).
