Script description

Langton's Ant

Two rules, ten thousand steps of chaos, and then it suddenly builds a road.

Panels: 52x16 and 32x8

What it is

The whole program is two rules. On a white square, turn right, flip the square,
move forward. On a black square, turn left, flip it, move forward. That is all.

For about ten thousand steps the result is an expanding mess with no structure
anybody has been able to find in it. And then, with no change to the rules and
nothing triggering it, the ant starts building a perfectly straight diagonal
highway — and never stops.

What to watch for

The wait is the feature. If you leave it running and come back, the highway
is the thing you will notice. Getting there takes a few minutes at the default
speed.

Settings

  • Steps per frame (40, from 5 to 200) — how fast it works. Lower to watch
    the chaos; raise it to get to the highway sooner.
  • Colour (190, any hue) — the trail colour
