The pattern on the outside is based on a very simple diffusion limited aggregation algorithm (http://en.wikipedia.org/wiki/Diffusion-limited_aggregation) and created with a program that I wrote. Diffusion-limited_aggregation can be found in a variety of natural systems including mineral growth and electrical discharge, as well as others. The organic forms created may look like some types of seaweed or coral.
I was inspired by some other example of diffusion limited aggregation.
Bit Player is a blog by Brian Hayes that I like to check now and again. He has a bunch of interesting articles on math and science and new ways of looking at things. The banner at the top of the page is based on the DLA pattern.
