After Dark Screen Saver: Penrose

The Penrose module from After Dark 2.0. I love the plastic look given to the Penrose tiles. A great module that shows off the math+art skill combination that Berkeley Systems infused into many of their savers.

PENROSE

This program fills the plane of the screen with a non-periodic Penrose tiling consisting of kite- and dart-shaped tiles in a five-fold symmetric pattern. The technique of deflation is used to replace successive generations of tilings with increasingly smaller tiles. See "Penrose Tiles and Trapdoor Ciphers" by Martin Gardner, or the January 1977 Scientific American.
