COMBO
Made a little arithmetic game in GeoGebra for my summer algebra students. (Basically Proof! except it always works.) Loving that there are always more than what I put in there. Play in GeoGebra.
Four Arrays
GeoGebra here. Not sure where the idea came from.
Shift
Mucking about with Riley's shift. Two different geometrically controlled shifts and one by function. The triangles are formed by a top edge of length 1 and a number from 0 to 1 identifying the opposite vertex. The function just takes the absolute value of the decimal part of the output. The geometric models use the control points to dictate the rate of the shift. Riley's is not a constant change, but an awesome effect. You can zoom in or out to get less or more triangles.

But, always the best, Bridget has the last word.
Color Array
Love this composition from Gregorio Vardanegra (seen via @lostfunzones) and wanted to play.
The squares are colored by hue, 0 to 1, up to the number c. (Mod(i,c)/(c+1)) The circle colors are from the function colors(x), applied to the index i then the same modular function. Shuffle mixes both lists and remixes each click. You can zoom in and out to get more or fewer. But it will only color the first 150! (Which can be fun in shuffle.) Play in GeoGebra.
And some more interesting functions...

Molnar Cards
Liked the apparent randomness of this Vera Molnar piece. In this sketch, the blue polygon determines the region to randomly select points, then there are random angles from 0 to A. If you click the sorted option, it organizes the points from left to right and applies the angles in order of size.
The original. 9 rectangles à la règle d'or.

The Umbrella Sketch
Loved the structure in this 1956 Willys de Castro "Boceto Final Para Una Pintura" and decided to approximate it. Really liked how the controls worked out! In my head it's now The Umbrella Sketch. Play in GeoGebra.

Archimedean 6-3-4
Made by dividing up the triangles into 30-30-120s and chunking with the squares to make a hexagon, altering with rotational symmetry. Unfortunately you usually have to zoom in to do the editing, and then out to see the structure.
Inspired by David Houlton's X tessellation.
