I reapproached my previous texture resynthesis program (see RWFC link) by making it more like cellular automata. Each pixel tries to figure out what it should be based on its surroundings and the input image. See the shader for a live version!

This is cellular automata. Typically you use just two states for each cell (alive or dead), but I was inspired to use multiple states. The results are fascinating!

In order to help me optimize the rendering and updating of hundreds of thousands of quads in my Haxe engine, I made these simple test scenes. By the end of the day, it went from 11 to full 60+ FPS!
