These automata follow a simple rule: Try to be the same color as those near me, and the opposite color of those a little further away. Slight biases vary background/foreground relations, and initial conditions determine other aspects of the transient and stable patterns (e.g. the random initial condition in Video 3 vs the approximately symmetrical ring set as the initial condition in Video 4).
