ElfYourself by Office Depot is a fun app that lets you put your and your friends' faces on a variety of dancing elf bodies. Once you've finished editing the faces, all you have left to do is watch the video. Laughs are guaranteed.
The process for capturing the faces is simple: take a picture of the person's face, fit it to the outline onscreen, and then indicate where the mouth is. This makes it so when your elf starts singing and dancing, the mouth moves in time with the song.
By default, ElfYourself by Office Depot only includes two songs for your elves to sing and dance to. However, from the app's main menu you can buy tons of other songs. In all, there are over a dozen different songs available.
ElfYourself by Office Depot is a really fun app that lets you create ridiculous videos in a matter of seconds. Looks like you just found yourself a new Christmas tradition.
