Sounds a little high for my pics.  I have very few lights, and the radiosity
is surprisingly quick.  I did some trials, and I think it might double my
time.  It also made them look kind of a nasty brown (increased shadows) in
places.  Maybe I'll do every 10th brick or so, with more in the lower
segments... Hrm
