Yes, I believe the function would need to be iterative in order to produce a
fractal pattern. Apparently one of the goals in camouflage design is to create a
pattern that works at a range of distances. You can see that this actually works
by reducing the size of sample images to simulate longer distance. This is a
really interesting concept to me.

I did in fact decide to cheat and use a sample picture. I used the eval_pigment
() function to obtain and reproduce the pattern for my use. I have attached an
image of the final result, which will be a background for a bumper sticker.
