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. :-)

I don't have the domain expertise or interest to know what's important or rare, and I can completely understand not wanting to hang on to it personally any longer, but that sounds like something a lot of people might be interested in, that ought to be exhibited somewhere, if (as it sounds like) it's work-oriented and not too personal.

Earlier quoted context omitted.

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.

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

I always took water for granted. In my country where I grew up, we had water available to us in the sink 24/7, 365.

Pure, clean. Drinkable.

As I am now traveling the world, I am experiencing places where water is not to be taken for granted. But only in mild ways. Not in actual life-or-death ways. That happens in countries I have not yet visited.

It’s weird. Most of my time at work I deal with pretty mundane things. And if I am thirsty, water is always available.

Water simulations are extra interesting to me now, because I am realising that in the future maybe I can help bring water to places where people are struggling because of unreliable access to water.

I think it would be very nice to be able to help other people on that way.

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?

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

that is crazy trippy in a fractal-y kind of way. very smart.

Would be neat if it simulated the air too. As-is, you can open up bubbles in the middle of the volume of water. Still a fun project.

I've realized that every few months somebody posts a link to one of the many (cool) things on oimo.io. I wonder what the next one will be :)
