  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.
