I know John Conway wasn't always fond of being known for GoL[0], but that doesn't make it any less important to me. I suspect for many, Life represents their first magical experience with programming. It can give the sense that you're glimpsing a connection to the deeper underpinnings of the universe. For me personally, Life has played a big role in my love of automata, and simulations in general.
I thought it would be fun for everyone to share their personal implementations of Life. Here are my meager contributions:
Recent hand-written wasm implementation (ui incomplete): https://github.com/anderspitman/wasm-life
Basic JavaScript/CSS intended to be used as self-contained animated icons: https://anderspitman.net/apps/golicons/
WebGL (for simulation and visualization) (unfinished): https://github.com/anderspitman/mogol/tree/webgl-sim
Two of my favorites that I didn't do:
