NARRATOR: You can find it in the rain forest, on the frontiers of medical research, in the movies, and it’s all over the world of wireless communications. One of nature’s biggest design secrets has finally been revealed.

NARRATOR: It’s an odd-looking shape you may never have heard of, but it’s everywhere around you: the jagged repeating form called a fractal.
