recursion_limit 2, and no. As I said, my computer is slow, which
discourages extensive testing. I'll probably do some spot testing (maybe
in that top corner) later, but the current settings are good enough to
work with.

Like any other room lit mostly by radiosity: lots of artifacts, even on
flat surfaces.

The radiosity is the only slow thing in my scene; without it, this image
would render in a couple of minutes, rather than several hours.
