Penrose by A. Karn and T DiZoglio..
©1992 Berkeley Systems Inc.
Part of the After Dark 2.0 collection.
Penrose is capable of generating some really beautiful patterns. This was definitely one of the more professional looking savers included in the original Windows release. With the various color palettes and a nice collection of patterns, although nothing really moved, it was still one of the prettiest modules available.
Unfortunately, Penrose seems to have a problem on modern systems. I tested this on three different systems and in each case, after drawing a couple of patterns, the module would crash with an out of memory error. So I had no problem generating a pattern for the above screenshot but this is no longer a module that I include in my normal cast.
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.
