I never considered it before, but by comparison this makes me realize that Conway's Game of Life is wave-based rather than particle-based. That is, in CGoL the rules apply to locations of the grid rather than objects traveling across the grid. I wonder if this system could also be constructed in a wave-based fashion?

Also, it seems like in this system the speed of light is infinite, since every particle acts on every other particle each frame, regardless of distance. In CGoL there is a speed of light, since cells can only influence their immediate neighbors each frame.
