You cheated, you used shaving foam instead.

The snow looks thicker than it probably should, but it is very very cool. It
needs icicles. Also, it looks like the snow fell straight down, does your
method allow you to defind a wind direction that would place the snow to one
side of everything?

We had a snow that looked exactly like this a couple days ago...all you
need is a damp snow that is constantly drifting straight down, with
little wind and no sun.

Very funny...

Isosurfaces!

I think he just used the trace() function going straight down from the
sky. Slanting the direction you give trace() should give you something
like that effect.

I think foam would probably need a bit less 'heavy' texture.

I don't think completely random would be good, but some 'jitter' could
probably help.

That's a good idea, thanks.

Just changing the direction would not be that good, because the snow
should much depend on tho slope, so you would have to take the normal
vector into account (right now it isn't used). Usually the snow on the
wind side of objects is thinner and less regular.
icicles would be nice, but they would involve pretty much calculation to
be placed properly.

Or maybe blobs would also do for that.

As i said in the reply to Josh, that alone would not be that good, at
least variation of the blob component size according to the normal of the
objects would be necessary.
I also think at some places like the 'N' in 'Snow' some 'surrounding
observation' would be necessary to avoid the snow overlapping with the
objects too much (right now i only use one 'trace' per component). Maybe
some components with negative strength could also help there.

Hi Christoph,
That looks very good, I always wondered whether something like that was
possible in pov. Would you mind posting the code?
Regards,
Thomas

It wasn't designed as a general-purpose macro, but there was aa good
example of making it snow posted to comp.g.r.r a year or so ago. I used
it on the image at http://www.hoboes.com/jerry/Gallery/Christmas.shtml
It's very christmas-card like, so might not be what you want. But I can
dig up the code if you want.
