Doesn't radiosity attempt to approximate this?
Ambient has a totally different meaning in a radiosity scene. It emits
light, It will illuminate nearby objects...

Hmm.. Not sure how radiosity works, but ... that would be the means to
do it. I've lit entire scenes with an ambient sphere before. It's slow
as molasses, but it does work.

Heh. I just started messing around with media. I've picked it up a few
time before and prodded at it, but never really attempted to get the
hang of it. It's certainly more tricky than radiosity.
