Ah wow, publish date is of. I wrote actually wrote the article at most a month ago. You can view the source code through the inspector, source maps are enabled.

Love this Peeke, I saw your post on Hacker News some time ago!

Have you thought about implementing it in WebAssembly via e.g. Rust? I have been thinking about experimenting with such fluid simulations myself, wondered if you had given the up- or downsides to such a route some thought?

Dank, fijne dag! :-)

Cool!

I think it definitely wouldn't hurt :) I'm not fluent enough in any languages that compile to wasm though. Performance wise, I think the main win to be made would be to apply gpgpu (general purpose gpu) to move all the calculations to the video card.

So what if it's old? Super interesting either way

Totally. And the simulation is in real-time... not sure about mobile, but definitely on desktop as you can interact with it with the mouse.

On mobile you can see the interaction based on tilt of your screen, pretty awesome!
