Accidentally discovered a flood fill based cellular automata while making a simple paint app.

I animated the flood fill (inspired by Mario Paint), so on click it slowly starts flooding in all four directions. But, when I placed two floods close together, they started colliding into each other, forming very organic looking patterns that ripple and shift. It's semi-stable: they can go for thousands of generations before eventually one floods "wins". Maybe some configurations are even stable?
