   Yes, photons+dispersion gives very nice results... but it's very slow,
specially if you add focal blur into the mix. Of course I will use them
on the final render of the cave, but I'm guessing a render time of more
than 12h...

   That's a very nice idea, if you have a window that catches morning
sunlight. Mine doesn't until 10 AM or so, but at least I've direct
sunlight until sunset.

   Ah... fortunately I don't read p.off-topic, so I can happily continue
to drink lots of coffee every day (and not only early on the morning).
