Carlo suggested this scene file for testing radiosity and it looked like a
perfect example for a kind of dome-like area light I made to the megapov
sources for povray 3.1g. I think I abandoned it because it really doesn't do
anything radiosity can't do with a recursion limit of 1. It seems to do a
good job with this scene in a relatively short amount of time though. This
uses an array of 91 vectors that processed like an area_light (I may have
changed something to allow diffuse calculation...it has been a long time).

According to the IRTC text file the original took 2 hours to render using
106 processors (1.9GHz P3s - 2.3GHz P4s) from Swinburne
Astrophysics and Supercomputing Farm, Australia. I assumed a render size of
1024x768 and used AA 0.03 from the quickres ini menu. Mine took 6h 27m 14s
using a Athlon X2 3.2ghz processor. It is dual core but the scene was
rendered in a single thread (peak memory used 14028998 bytes).
