Thanks. I rendered the source you posted on this thread, with 3000 
samples, confidence 0.99999 and variance 0.00001. And colored spheres :P 
Took four hours. I'll attach it to the *next* message.

Well I don't think I would attempt it either :) Last time I looked at 
the code, I saw focal blur code was scattered all over POV instead of 
self-contained somewhere... But maybe that was just me.
