Yes, I know what you were getting at, and you are right. I used just the right
ambient to make the smoke look like it's disappearing. It only works good if
the ambient value matches the objects behind the smoke.

I had interesting results too, but not very realistic. Perhaps a spherical
pigment with high ambient values can be translated on the isosurface where the
light_source is to produce a more realistic effect. It would be cheating in a
way, but it would probably look good.
