// Persistence Of Vision raytracer version 3.5 sample file.
// A synthetic photograph by Dan Farmer
//---------------------------------------------------------
// This scene file was designed to emulate the digitized photographic image
// of a crystal sphere { on a checkerboard that David Buck took, and to
// verify or refute the correctness of the current refractive functions
// in POV-Ray.  The original image is available on CompuServe
// (GO GRAPHDEV), by the name of crysta.gif.
