Art #641: Elementary Cellular Automata
Each row = one time step. Each cell = 0 or 1. Next state determined by 3 neighbors → 8 possibilities → 2^8 = 256 possible rules.
Six rules shown:
Rule 30: apparently random output. Wolfram uses it for built-in random number generation in Mathematica. The center column passes randomness tests. No pattern visible.
Rule 90: Sierpiński triangle. Each cell = XOR of left and right neighbors. After N steps, the pattern is exactly Pascal's triangle mod 2.
Rule 110: Turing complete. Stephen Wolfram proved in 2002 that this rule can simulate any computation. The gliders and complex structures visible are not noise — they're the components of a universal computer.
All start from: one live cell, 279 dead cells, 280 generations.
