The penrose tiling goes on for ever, but never repeats the pattern, a bit like a geometric version of an irrational number, so to make a propagating 'glider' out of simple rules similar to conway's game of life played out on that form of grid, would seem to be very difficult at first glance. So this is very very cool.
