An experiment towards fluid simulation gone awry. Started as a modification to this bird flocking example in an attempt to work with multiple render-to-textures. In testing to see if the two textures were able to influence each other through the gpu, this happened. It's almost gpu advection, and accidentally beautiful enough to keep.
At increasing resolutions the overall effect transitions from something like ice freezing, to the arcing electricity of a Jacob's Ladder, and eventually lands on a nicely organic smokey effect.
At resolutions that are not powers of two, a lot of the stability goes away and what's left is closer to falling sand.
