Thanks for the interest! Feedback is a real motivator - if people are interested
in more, I'm more likely to take it further. Not that I'm not interested in it
for my own sake of course, but real life is so tiring :)

I think what I meant was just to use radiosity to provide all the light, i.e.
have emissive blobs (maybe hidden using no_image) rather than light sources.
This isn't an UberPOV-only option, it just works better than in base POV-Ray
because I don't have to worry about radiosity artifacts.

There was an UberPOV-only option - use lots of distance-faded light_sources.
This can also be done in base POV-Ray of course, but UberPOV allows such
light_sources to be ignored over a certain distance away, which turns a dog-slow
render into something feasible.
