IMAGE DESCRIPTION:A high speed rifle bullet "ruins" a glass made 
of glass. Just milliseconds after initial contact, the action is 
frozen by a strobe-flash just as cracks are propagating from the 
point of impact.  

For this competition, I took a different tack and modeled things 
that Moray/Povray do well -- metals, proceedural textures, and glass.
I usually end up spending 80% of my time modelling and texturing and
20 % of my time in composition and lighting.  This time I flipped the 
ratio and played a lot with various lighting schemes and odd things 
like focal blur (there's NO AA in this rendering -- all focal blur!)


DESCRIPTION OF HOW THIS IMAGE WAS CREATED:
Glass is a rotational spline in Moray.  Walls are thin boxes, floor is 
a plane.  Textures are highly modified Moray standard textures 
(Old glass and marble?).

Three useful techniques worked out well for me. 1) Bullet motion 
blur is a scaled cylinder with a gradient pigment going from 
transparent to brass.  2) Cracks in glass are CSG'd with 
translational spline "cracks".  3) FINALLY got focal blur to 
work w/o totally cranking the image's gamma thru the roof 
(Yeah, I know this bug is fixed in the megapatch, but I 
started in this Povray version didn't want to change in mid-stream)
