Very good! Seems that Kari is a great inipiration for all us. I'm trying
to finish a macro for this kind of kari-lights, which I started some months
ago inspired by Kari comments.
I'm also playing with another Kari idea, and that's using spectral data
for the lights. His original idea was to wrap spectrum pictures on a sphere
containing the light. But that was slow, so I searched the net and found an
algoritm to convert a sampled spectrum into rgb, and it seems to work
pretty well for common bulbs spectrums (feven luorescents come out
greeninsh!:). The problem is that I never seem to be even close to finish
the macro: RL is a bit annoying sometimes... hope to have something decent
to show soon.
