Wow.  You truly are able to maintain meticulous focus, and apply your knowledge
and creativity to addressing these kinds of issues.

If not actually photographic, every one of these images is textbook-quality.
That lamp looks _real_.

I'm sure that all the work you've done on this so far could fill an entire
chapter in a computer graphics textbook.   Certainly an extensive blog post or a
monograph on faking ambient occlusion with POV-Ray...   ;)

Great work as always, Richard.
