ionreq creates generative forms, textures and particles through programming. One of his series it is called SmoothLife which is a generalization of Conway's Game of Life ionreq discovered while playing around with GPU programming. He explains how it work in this video. You can download the source code and Windows executables from sourceforge (links in his youtube channel). I specially like the 3D series of SmoothLife which show organic and colorful digitalized creatures moving and reacting each-other into a cube. See more;
