Using cellular automata for livecoding

So I’ve been thinking about creating a big and complex cellular automaton for livecoding as I really like 2D systems like orca. The reason I want to make it complex is because I’ve tried making music with simpler automata such as wireworld, but that takes forever to create anything interesting in, so it isn’t quite that good for performance or quick and dirty prototyping. Any thoughts on this? Any similar systems? What kind of features would you like this system to have?
