ok - this is live now

that's a great idea for a feature - we could make that "swipe down" -- https://github.com/rulehunt/rulehunt/issues/170 should cover it

Hey everyone — I’m one of the creators of RuleHunt

This started at the https://alife.org/ Hackathon in Kyoto as an experiment to get a more intuitive feel for how unique cellular automata patterns like Conway's Game of Life really are. Each browser runs automata simulations locally using WebGL (via GPU.js) with CPU fallback.

We’d love feedback on ideas for ranking or clustering interesting rules — right now “interestingness” is purely human. Thinking about adding simple metrics like entropy, density, or temporal variance to help map the space.

Happy to answer any technical or design questions!

Do you have benchmarks? How much of a difference does it make?
