    Ah, fond memories: https://akkartik.itch.io/carousel/devlog/702311/all-the-1-d-...

    Only benefit over OP: pinch-zoom on a multi-touch screen.

    Cool! Would be nice to get some explanation for this though.

    These are Wolfram's rules, though?

    How are they sorted here? It's kind of sorted by number, but then there's discontinuities in the numbering?

    Also I wonder... Most of them aren't doing very interesting things, maybe there's a way to detect trivial loops and filter those out? (Maybe compression, as mentioned here https://news.ycombinator.com/item?id=46942864)

      These are all 256 rules. Where do you spot discontinuities? Also, each rule does show compressibility and other metrics like entropy

        Well, I didn't know there were 256 rules, I don't know how that works, and I'm one of the luckier ones who has heard about this stuff (but not much)!

        My point: add some context please, either as a top level comment, or much better, on the actual page.

        As a stopgap solution for others:

    This is awesome, and is something I've been working on small demos for.

    The stats are cool, could use definitions - especially for Entrophy, as that confuses most and can be defined arbitrarily, although the central tenet is basically the ability for the output to be GZIP vs random output.

      Definitions are there if you hover on them.

        i seem to be missing something crucial, how do i interpret the truth table? assuming green means "becomes white", trying to step through rule 1 i get different results
