One of the most popular holiday websites from last year, ElfYourself has launched again, this time with support for four dancing elves. Upload a headshot for yourself and three friends to have your heads transplanted onto the bodies of a troupe of dancing elves. Another new feature is the option to add your own voice message by calling a phone number and recording it over the phone. The final result will give you a fun clip of the four of you dancing a little routine that you can e-mail off to friends. And although they do dance together, you'll see that each elf has his/her own steps.
