From the developer:
Get into the Christmas spirit with this jolly 3D screensaver which features Santa delivering presents in his sleigh. However, Santa is a slacker, so as the reindeer pull his fat butt thru the sky, his friendly elf sidekick does all the hard work. With heaps of configuration options including a countdown to Christmas day, and over 50 Christmas carols as background music that will really set your teeth on edge, this is fun for the whole family.
