Mac OS Entertainment
Let it snow on your desktop and have Santa and his reindeer fly around your screen for that Extra Festive Season Cheer, while snow piles up on top of your windows (really!) and at the bottom of the screen. Maybe there's a polar bear somewhere too.
There are lots of options to control the snow fall, the wind, Rudolf's red nose, the size of the snowflakes, Santa, the bear, the snowdrops, etc.
Optionally you can have snow on your second display too.
NOTE: iSnow works fine on 10.8 (Mountain Lion) too. If you have trouble starting iSnow you can hold down the option-key while starting the application. That will reset the settings.
iSnow Classic, the classic Snow since 1984.
