Multiple ants with different rule strings — watch emergent highways

Step: 0
Rule strings define behavior per color state: L=turn left, R=turn right, U=U-turn, C=continue. The cell color advances to the next state each visit.
Classic Langton: RL — chaotic first, then builds an infinite highway after ~10,000 steps. LLRR — builds a highway almost immediately. LRRL — spirals outward. Click to place a new ant at cursor position.
