Here are some of the images I have generated for the Cornell box.

depth 1 sample 4 samples 16 samples 256 samples

These were generated with the entire ceiling as a light source. Also, I used a cosine distribution for the reflected rays. I don't like these images at all.

This next image was done with a different matrix (the transposed glassner matrix that Doug came up with). I used 64 samples per pixel, and took reflections to a maximum depth of 64. I have no clue how long this took to run (I must have forgotten to run time on it), but it was probably around 8-10 hours.

Again, I felt like that image wasn't very great, so I traced another one (using RGB this time), using 512 samples per pixel, and going to a max depth of 8 reflections. I really like this image.
