Hmmm... Polarized light might be an idea for a feature to add. I've seen
some interesting effects as a result of using polarized light; things like
sticky tape can look really beautiful when viewed using polarized light.

Maybe it could be added to POV, but as you just said, it would be too
difficult to bother with.
