Uel, Here's a screenshot of me viewing your screenshot.
Wish my hardware was fast enough, I'd post a "screen movie" of this so you can see the snow coming down. It's actually a good match for the wallpaper and the kids DIG it.
One without cube
For those not familiar with the snow plugin for compiz, it's pretty neat as each snowflake has a mind of it's own as they come down. Some even get bigger like the are coming towards you. Pretty realistic effect. Not something I'd normally use, but "Tis the season".
