There's only 3 more values per ray for a more realistic simulation
of light; amplidude/frequency/rotation around axis of travel...?
Could probably do some interesting things with having materials
change the frequency of the light...

Speaking of something completely different...iridescence.  It's
an interference pattern between two surfaces of oil or similar,
how 'bout trying to do that the hard way in POV?  Should be
doable even in 3.1g...I think I'll play around with that and
such when I get back to my computer.
