I've recently become obsessed with cellular automata. I've made a wireworld sim, a cyclic automata, an averaging cells one (don't know the real name for that one), and rules 31, 90, and 184. The only big ones I haven't made is Conways Game of Life and Langton's ant.
For an AS3 contest a while back, I made a 3D cellular automaton. The contest was to write something cool in 25 lines on the first frame of a CS4 timeline, so just paste this there and run. Mouse rotates, click to reset
