The Mandelbrot Set

I was looking through wikipedia a couple of days ago, and I found what struck as the most beautiful, complex thing I've ever seen. The Mandelbrot set - a fractal, a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole. Self-similarity when you zoom in, essentially. But check this out.
































Awe-inspiring, huh?
