Check out the cool fractal(s) on the cover of Autechre's ep7 CD (7.1 & 7.2 front and back cover). Wikipedia article on ep7 has a link to the warp records website which produced the album. The website has an animated Flash video of the fractal formation, step-by-step. Apparently it was designed with the help of a circuit designer. You could google image search for it also.
