Looks nice but not like water. It keeps moving forever. A bucket of water would stand still after a few minutes. Edit: Seems to lack simulation of friction between water particles?

Came here with the same nitpick. It settles down too slowly. Also takes too long to start moving after changing angle. So it's in this weird spot where it's both more + less reactive than real water.

Just seems like some fun art to me, could have been named anything.

this is still my favorite. https://oimo.io/works/life/ That dev has a bunch of cool projects.

I would like to check later on if the rules for this "cellular automata" (if it is one) are documented and the fractal nature naturally concludes from it or whether the fractal was simply manually forced when you zoom a certain level.

this one is much smoother: https://paveldogreat.github.io/WebGL-Fluid-Simulation/ previously: https://news.ycombinator.com/item?id=34422948

It also decouples frame rate from simulation speed so even if frames are dropped the whole thing doesn’t feel sluggish.

My dad worked on the Apollo program In The 60s. They were using analog computers to simulate fuel slosh in the tanks. He also had a flight sim display that allegedly could go from space (earth as a circle?) To low level horizon and grid. I never saw either but am about to toss schematics for the later with the rest of his stuff. Personal note - he died in '03 and I'm done hanging on to stuff. :-)

You should upload them to the Internet Archive.

And/or donate them to somewhere that'd be interested in preserving them.

Wow, that is so cool! I’ve fiddled with Conways game of life a lot, implementing it recursively in SQLite, various languages, explored variations of it; I knew you could simulate it inside the game, but this is mind blowingly cool! And it’s so smoothly done, it’s like stepping through the looking glass.

Funnily this is usually something you need to fix in water simulations like this one since a lot of solutions have artificial too rapid energy loss. So the fact that it acts this way is sign of more mastery rather than less (it’s trivial to reduce energy faster).

Interesting. Sometimes pockets of not-water (vacuum?) appear in the middle of the liquid. Based on observation of real water, such cavitation would not form in water splashing around in a bucket.

You mean a bubble?

I’m pretty sure it’s manually forced, but I would be delighted to be educated otherwise.
