I got the scene working (see "Phun With Photons" in binaries.images) by
extending the media container to the right to enclose the light source. At
least I think that's what made it work.
As far as the second light source causing no photons to be shot, here's the
scene file. I'm not sure what part of it would be useful, so I'm posting
the whole thing. Pardon the sloppy code. The second light source is just
after the camera declaration. If "reflection off" is set in this light, no
photons are shot. The scene requires "kolors.inc" and my "mega_metals.inc"
but colors can be changed if you don't have these.
