The easiest (gulp, not really) way to do this is make a particle system.
For the particles use triangles, although they sound rather primitive, they
do produce a good looking snow because of the way the light reacts with them
as they tumble.  It might be hard to simulate this with POV-Ray.  I oce
tried to make a particle system with POV-Ray but ended in failure.  The only
really good snow I was able to make was with MAX's particle dynamics.  Once
again, I used triangles (although facing triangles are a good way to start,
by facing I mean camera normalised).  This is the best way to go about
animating it.  If you're planning on doing any kind of animation it's best
of have a particle system (perhaps POV-Ray's macros would help, I've never
used macros so I wouldn't know, I presume it's like MAXScript, in which case
it would help tremedously!).  There are a few particle simulators out there
but I'm not sure if you could convert the particles to POV-Ray.
