This falling sand game runs a particle simulation in rust compiled to web assembly and WebGL for fluid simulation calculated on the GPU (hope I remembered those technical details right I read it ages ago) https://sandspiel.club/

Plus it’s strangely addictive.

The creator even wrote a blog post describing how he made it. Press info on the top right to get an awesome breakdown of his approach.

Immediately thought of Powder Game, and it turns out that it's one of the main inspirations indeed (according to the info box)!

I spent so many hours in that game. It also had ways to publish your creations, and people created anything from multiplayer coop games to entire ALUs in it. Good times, and thanks for linking the remake!
