Finally got a new shadertoy up!
Your typical grid based incompressible fluid sim with the exception of the pressure term being solved in one pass, which posed a good challenge but not a solution you'd want to use in a real scenario. Normally you'd iterate through many passes but that's not an option here.

Also put up a showcase on my website.
