Is the Primordial Soup Done Yet?

More technically: each cell counts how many cells in its neighborhood, including itself, are of color 1; call this *k.* Then in the next click it becomes color 1 with some probability *p(k),* with *p(0)* = 0 and *p(k)* = 1 - *p(5-k)*. I only used the case where *p(1) = p(2) = 0.5.*
