Procedural Comet

This is my favorite example of getting a lot of landscape from a tiny bit of code. Even the white stripes are the result of the physical transformation which creates the surface manifold.

It is a simple fractal, best summed up with a poem:

Big whorls have little whorls
That feed on their velocity;
And little whorls have lesser whorls
And so on to viscosity.

-Lewis F. Richardson
