Well, here is another test render. This time it only took 6 and a half hours,
but I rendered at a lower resolution and with less antialiasing. I am using my
everyday PC but it has 2 cpu cores so it doesn't have too much of a detrimental
effect on the other things I am doing. Plus if I leave it going overnight I
don't seem to notice at all...

This render uses no radiosity. I also toned down the phong highlight a bit,
although maybe I didn't need to. The reflection on the ground has not been
changed but now I am using an HDR background so the effect is more pronounced.
I used TGQ's light dome method that I mentioned in an earlier post, to generate
the lights from an image. It is not too slow for parse-time with only 32
lights. If you're interested his post was on 14 May 2007 in p.b.s-f:

The probe I used was The Kitchen by JVP (available at ignorancia.org). The glass
texture is based off an IRTC entry by Tek in 2005. Many thanks to all you
amazing people!
I still have a few more tweaks before I re-do the final render.
