Evolution of cellular automata, continued

The behavior of all 256 possible cellular automata with rules involving two colors and nearest neighbors. In each case, thirty steps of evolution are shown, starting from a single black cell. Note that some of the rules are related just by interchange of left and right or black and white (e.g. rules 2 and 16 or rules 126 and 129). There are 88 fundamentally inequivalent such elementary rules.
