Rule 30 is a one-dimensional binary cellular automaton rule that displays aperiodic, chaotic behaviour. This automaton is of particular interest because it produces complex, seemingly random patterns from simple, well-defined rules. Wolfram (A New Kind of Science) believes that cellular automata are the key to understanding how simple rules produce complex structures and behaviour in nature. A pattern resembling Rule 30 appears on the shell of the widespread cone snail species Conus…
