Basicly a test of indigo0.6 test6. Very fast compared to older versions.
I let this render for about 1 and a half hours on my:
dual 2.8ghz cpu
Took a while to tweak the white balance and tonemapping parameters to match the original cornell image. http://www.graphics.cornell.edu/online/box/box.jpg
I admit there is still some visible noise, but other than that, I think it turned out quite well.
