Hyperbolic Kaleidoscope: 2-3-5 by Chaim Goodman-Strauss

This image is from a Kaleidoscope you can actually build! Here the hyperbolic wall paper group *22222 is illustrated. Any 2- dimensional discrete hyperbolic group of reflections can be physically rendered with one of these scopes. Unfortunately, one needs cylindrical mirrors, which are hard to find and cut up. By the way, reflection in a circle or sphere is not inversion but some strange map that preserves the combinatorics. For more information, see Unusual Kaleidoscopes

How to make it: Drafted and raytraced in SoftImage.
