This is a simple picture I made to experiment with focal blur, made out 
of a picture that I made to experiment with glass. It's funny that 
rendering this with focal blur on my new box is roughly 2 or 3 times 
faster than just rendering normally on my old box, but I guess dual 
Opterons and a Gig of RAM will do that :P I'm pretty sure I've got some 
settings all wrong, and I'm still not too satisfied with the blur, but 
this is the best I can do so far.

Scene contains 3 frame level objects; 1 infinite.
