// "No More Chrome Spheres Please!"
// Copyright 2001 Rune S. Johansen

// The "chrome sphere over checkered plane" is an overused raytracing cliche.
// The last thing we need is another of those images...
//
// ...but who cares! ;)

// NOTE:
// First render the file SIGN.POV and then render this file.
