I didn`t see any snowflakes. I`m using Firefox 2 on a Mac. I even waited a while, 30 seconds or so, to see if they would load. Nope.
I checked it in IE where it works, but it doesn`t work on FireFox 1.x,
either. As for the falling snow, it`s not that much of a distraction,
and it adds some fun to the winter thing. The only problem you might
have is that a fairly large section of both the country and the rest of
the world experiences winter without there being any snow. So it`s more
a personal choice on your part. Not distracting, just a choice.
Maybe they`re thinking they should get their eyes checked---they`re seeing spots before their eyes?
