Reductionism is fun! Many interesting attributes can be discovered when we
look at the pieces of a system as pieces making up a whole. Emergence and
the like are fascinating .... Thank you for your comments!

It would most *certainly* be possible with a program loop. However: not only
was the idea to use parallel mirrors appealing, it turned out that I gained
an extra bonus. The mirrors are not precisely parallel: the far mirror is
y-rotated by 0.1 degree. This provides the wonderful
curving-off-to-the-right extent of the "passageway". This would have been
much more of a pain in looping through objects, because of rotation,
placement, and checking the intersection for problems. Also, I could easily
have added x-rotation to curve "upward", for instance.

Of course .. this led to the slew of problems ("challenges") I had to deal
with. The radiosity left smears from the Japanese characters, so I had to
do two passes, saving radiosity, and loading. Also, the texture was
reflected in the mirror which led to a terrifically ugly Rorschach pattern.
So I ended up doing two seperate renders with same settings, and pasting
them together over the mirror seam with Photoshop.... I know it's crude,
but I'm pleased with the results, and it's +/- exactly how I intended it to
come out.

Again, thank you for your comments.

ps. For more behind-the-scenes ... take a look at this early render in the
process. (Made with a Real Point-Light!)
