  I used ambient 0 for the four object plus the floor box. Little too dark
for my tastes so I used a shadowless fill light in addition to the spotlight
shining onto the 'mirror'. I differenced the backside of the mirror during
an earlier test rendering because the reflective caustics were putting light
where I didn't want it to show when I was experimenting with additional
lighting placement.

  Thanks to everyone for the kind comments. Don't use my photon mapping
settings as gospel. I have tried to read all of Nathan's posts concerning
appropriate settings but I may have changed too many items at one time and
quite possibly went the wrong way...<s>. Many thanks to Nathan for his
fantastic work on implementing photon mapping into UVpov.

  I did find one shortcoming during final traces - I need more memory! I was
hitting the swap file much too soon with 64mb RAM. Here are the stats for an
800w by 600h, +am2 +a0.2, on a Pentium 200MMX.
