Unless you used heavy anti-aliasing, you would get moire effects. I am
not really certain how multiple sources would interact with small-scale
pigments though...could be interesting.
If you did use anti-aliasing, I think the color would tend more toward
50% gray.(unless you used unusually bright colors)

Hmm, maybe for simple shapes, and images which don't have to look
super-realistic.
It would also be useful for simulating rainbows from objects out of
view...

I hope that this makes it into MegaPov soon, I can think
of many uses for it, such as you have a garden and you
want it to look asthough the sunlight is shining through
the trees behind the camera, but you don't want the
added parse and render time that you get with trees, or
you want a room with blinds on the window but don't
want to see the blinds, etc, etc. You could do
a real good disco animation with this. IMP should love
this feature, light patterns on a moving vehicle, wow.
Keep up the good work.
