Ah, good point about crossing. Each individual actually faces enormous local selection pressure, so once a given triangle converges closely enough, offspring just aren't going to be selected upon crossover with a (possibly very different) neighbour. So actually I think this demonstrates a kind speciation in a very sharply divided landscape. It'd probably work better on simple images with smooth gradients and the like.
