A simple scene with no light source, but the dull colours of the skysphere are
made vibrant by the physically impossible hyperreflectivity of the object. Nice
to play some trance to. :)

The .avi is at a higher resolution and shows higher colour definition, but won't
post here.

Interesting. Would you be willing to let me get a look at the source?

The source (which doesn't include the .inc file of the geometry - nearly 400
lines) is:

// Persistence of Vision Ray Tracer Scene Description File
// File: HyperReflectivity.pov
// Vers: 3.6
// Desc: Hyper Reflectivity Example using 200(CC)-sided shape

global_settings { assumed_gamma 1.0 }

#declare R=32; //reflectivity factor and skysphere colour diminishing factor

camera{location z*-2.5 up y direction z right x*image_width/image_height look_at

sky_sphere{pigment{gradient x+y-z

object{intersection{object{CCIc} object{CCTH} object{CCHI}} pigment{rgb 1}
finish{diffuse 0 specular 0.5 roughness 0 reflection {R}} rotate(360*clock)*y}

//end of file

You are welcome to replace the object with one of your own, and to see how this
looks for other values of R.

The .avi of this file (via VirtualDub at 10fps) weighs in at 506,267KB
