Langton's Ant

Langton's ant cellular automaton, in C.

A small, self-contained demo written in pure C — no external libraries, just the standard library and POSIX. Part of the Corg-Labs collection of single-file C programs.

How It Works

1. The ant turns right on a white cell, left on a black cell
2. It flips the cell's color, then steps forward
3. Order emerges into a 'highway' after ~10,000 steps
4. A live counter tracks the number of steps taken
