Okay, this is site where you can create a little animation that puts your face, the family, or even the dogs face atop an elf's body and it does a jig. It has a cuteness factor... at least the first couple times. Very simple, takes about 3 minutes to create your own elfing greeting.
Here's one I made of the dog as he went from pup to 9 months old, wife just about died laughing...
