What you get here is a rather sharp image with a halo 
(the blurred image) around it. You don't get this result with 
the POV-blurring techniques.

Milk etc is almost opaque, so you don't see any blurring.
If you mix it with a lot of water, so you can see through it, the 
blurring becomes insigificant again (I just tested it).

IMHO if you don't perceive it as blur, it isn't blur, at least
the context of graphics.
