I generated this image the other day when messing around with my CUDA 2D fluid simulation code. For the technically minded, it's the magnitude of the velocity mapped to a color gradient, the velocity field has some turbulence added using curl noise. For the non-technically minded, it looks like THE BURNING FIRES OF HELL!

Nice. Could you elaborate on how you added the curl-noise?
Very very nice Simon!!
dlai - I'm simply adding curl (aka divergence-free) noise to the velocity field. It's the curl of 4 octaves of Perlin noise. The original paper and source code is here:
