Cyclic.5

A cyclic cellular automaton (CCA) is defined as an automaton where each cell takes one of N states 0, 1,…, N-1 and a cell in state i changes to state i+1 mod N at the next time step if it has a neighbor that is in state i+1 mod N, otherwise it remains in state i at the next time step. The cells are arranged in a bidimensional grid and initially they are in a random state. At each generation a cell in state i evolves to state i+1 mod N if at least one of its neighbors is in state i+1.
