Decades ago, when I was a child, I *invented* a lamp of darkness, that
is, of negative light. Needless to say, decades later, when I first
found POV-Ray (3.0 was just released), I used it to visualize my
invention, and, needless to say, POV-Ray worked perfectly.
Now children invent substances where speed of light is higher than the
speed of light.
I call it "progress".

Not at present, but there should be.
Maybe Wiki page with sections devoted to POV-Ray "members" who have had things
published, and then just things like papers or journal covers that used POV-Ray
to render the graphics.

excellent idea, I agree, a page / section listing papers and articles would be
good, make a "fine resource". write.

I've tried negative IOR in POV-Ray, and it make the object a perfect
mirror. ANY IOR <0 result in reflection.

...that's how you invented fiber optics. Now it's time to invent ATR
spectroscopy ;-)
