Elf Yourself by Office Max and Jib Jab will go live Nov. 11.
It's free.
Simply upload a picture of yourself and up to 4 friends and it will make a music/dance video for you.
NOTE -- YOU CAN EDIT THE SHAPE OF THE FACE -- HOWEVER, IF YOU BRING THE CHIN LINE UP TO FAR YOU'LL BE ABLE TO SEE THE REAL DANCERS FACE AND IT WILL LOOK REALLY WEIRD.
The online version will expire in January 2012.
