Reminds me of those cool visualisations that Winamp had, think they were called Milkdrop?
There is also the open source reimplementation of Milkdrop called projectM, which might be of interest to you.

Re: WebGL Fluid Simulation
#32Wow so cool. Any summary on how the algorithm works roughly?
The repo refers to this article: http://developer.download.nvidia.com/books/HTML/gpugems/gpug...
Looks like it's standard Navier-Stokes.

#34WOW! Not only is it FAST, it does multi-touch too! Successfully did 4 fingers already, although saw it somewhat slow down but not much. On a beefy system this could probably handle the full 10 point touch no problem! I am doing this on a desktop (Arch + Gnome 3) with an Acer touch display. Well done!
Woah, you're right. I just tried it on my Pixelbook screen (keep forgetting it's touch screen), and it handling as many fingers as I could give it (all 10) with no lag.
I'm guessing the number of inputs doesn't really influence simulation speed since the shader runs each frame for each pixel anyway. When touching the screen, some pixels are changed to hot/colored, but that doesn't really change the amount of computation needed to simulate the whole screen.

#35Whoa this is jaw dropping on mobile. Try typing in a density diffusion of .996 and setting velocity diffusion to 1

#36I tried this on my mobile phone, expecting it to not work properly, but everything was super-smooth. Impressive.
I know right.
So then I tried multi touch on my iPhone. Five fingers smooth as can be..

10 fingers on ipad pro, no slow down.

I'd be a little surprised if multittouch affected performance significantly. It's probably simulating and rendering every cell every frame regardless. I couldn't notice a slowdown on my phone with five fingers.

You can crank up both resolutions to maximum on a recent mobile device and expect 60 FPS. That plus all 10 fingers on an iPad looks pretty cool.
