I haven't seen many multi-type CAs in the past

Those are the only ones that really interest me; the single-type ones usually don't have the same sorts of complex interactions.

If you want to see the interactions change, play with the numbers in the arrays in the values of %t (where it is defined at the beginning of the script). These numbers effect how each type grows or reproduces, how long-lived each cell can be, and how easily they die from isolation or crowding. Not necessarily in that order, of course. The numbers in the version I posted give a fairly interesting scenerio, but I'm sure there are other possible sets of interaction to uncover. For example, maybe the symbiotic + and x types are too robust, and perhaps the fast-growth type is too wimpy. Perhaps if their numbers were tweaked a bit, you could get a more stable environment where they can all co-exist for a longer period of time...
