The site, which lets you affix your head (or even your boss's head) to a dancing elf body is back again, and this year, in addition to adding some new dances, Elf Yourself is also integrating with Facebook and Twitter.
You can now tweet a link to your Elfish-creations on Twitter, post them to your Facebook wall, or e-mail or embed the videos onto your own website. You can also sign-in with Facebook Connect and use your Facebook photos in the "Elfing" process.
