Great work! I build[1] a classic javascript interpreter for Langton's Ant a few years ago. Just updated it to include support for custom rules. Thanks for reminding me about Langton's Ant it is always cool to recall things one build in the past.

BSPSPSPSPSP - This program/configuration appears to execute a random walk. Hard to be sure.

My versions of the same fwiw:

- https://jcorbin.github.com/hexant -- the hexagonal one I'm working on now

- https://jcorbin.github.io/ants -- the square grid one I made several years ago

Love it! Here are some cool patterns:

  * RPB - Looks like a 3D printer printing a bowl of Cheerios
  * PRLL - Simplest Eastbound highway
  * BRSS & BLPP - Nearly space-filling hex spirals

I'd love that as an animated android background.

So this is how the universe's only electron updates the state of every atom! Maybe.

Well, it's deterministic, because the program is deterministic, but it certainly does look random.

Thanks! I have also discovered a pattern that is fully space-filling: BPBBP - will slowly fill the entire screen with a growing green hexagon, with a single yellow dot at the origin.
