Just curious, but what radiosity settings are you using here? Just recently
I was trying to make a scene using radiosity and no light sources, but it
seemed that no matter what settings I used I couldn't get it to look right
(as you have here).

radiosity {
brightness 1.5
count 100
error_bound 0.15
gray_threshold 0.0
low_error_factor 0.2
minimum_reuse 0.015
nearest_count 10
recursion_limit 5
adc_bailout 0.01
max_sample 0.5
media off
normal off
always_sample 1
pretrace_start 0.08
pretrace_end 0.01
}
but I had an area light too.

The radiosity settings could be much better.

FYI... If your radiosity+glass scene has dark circles (e.g. bottom of
the rear box), try increasing your max trace level... that can sometimes
get rid of the dark circles.

I saw all the artifacts, it's not really the settings,
I forgot to put an inverted sphere in for background,
so there were some infinite rays...
BTW, the bunny mesh had lots of "sparkles" since
there were way too many verts and no smooth triangles.
I tried to filter about half of them out, and re-scaled
it larger in the mesh. Some post-processing... took
about 45 mins to render for me.

I was dinking around with Cornell Boxes before. Yours turned out better than
mine.
