um... subject kinda says it all.  i remember way back when, there being
the whole question of modelling a sparkling diamond.  the proposed
answers hinted at rendering the scene 3 times.  once with a red light,
once a green, and once a blue.  then composite them.  of course, each
render would see the light's wavelength altered such that the images
would be different.  unfortunately, i don't remember how this could (or
IF it could) be accomplished
