Just imagine taking a 3D grid, getting the color of a pigment at each
"node", and moving that node a certain amount depending on the color.
I actually used the color vectors to store offset vectors, the color_map
interpolates between them.
I provided a variable to "scale" the amount of motion down. I can turn
it up so you end up with a unrecognizeable, tangled mess of cylinders
and spheres, or scale it down so you have a slightly jittered grid.
BTW, this also demonstrates a possible feature I have been thinking of
trying: some kind of "displacement" warp for textures, and maybe even
the ability to warp meshes(if I can figure out their code). Not quite
"displacement mapping", but close.
