Hey this was also the first fluid sim paper I ever implemented! I haven't done any grid-based simulations (except maybe the classic "Real-Time Fluid Dynamics for Games" by Jos Stam), but I've been able to greatly improve compressibility by using "Position-Based Fluids" by Miles Macklin. Someday I'll dive into WebGPU and post a JS version on HN...

I like the different fluids in your sim though, I may try that myself.

Very cool! What does the changing color of the fluid indicate, particle velocity?

I believe specific gravity.

Things like "how do you properly make a B-52?" ( http://www.cocktailhunter.com/bartender-guide/specific-gravi... ) or a Pousse Café ( https://youtu.be/4OJd_phsa5w )

Yes, particle velocity! I believe this clip is after I implemented metaballs too, so the particles blend together to make it feel more fluid-like.
