If you're finished with your Christmas shopping and sitting around with your family drinking eggnog today consider downloading SantaSnaps, a fun Photo Booth application that allows you to "dress up" as Santa, the Nutcracker, a reindeer, a funny elf or a combination of the four.
To use the application you click on the Santa Snaps icon, take a self portrait using an iSight camera (just open Photo Booth on your MacBook) and add some holiday cheer without spending 20 minutes Photoshopping the picture. Santa Snaps is a free application, but if you feel like giving the creators accept donations. Download it at Cocoa Duel. Make sure to check out their other fun downloads too!
