Elf Yourself is a 2006 American interactive viral website where visitors can upload images of themselves or their friends, see them as dancing elves, and have the option to post the created video to other sites or save it as a personalized mini-film. The video and website were created by Evolution Bureau (EVB), in collaboration with New York company "Toy." for Office Max's holiday season advertising campaign. The Elf Yourself website and advertising campaign first launched for the Christmas holiday season in early December 2006, and has returned each subsequent season. According to ClickZ, visiting the site "has become an annual tradition that people look forward to".
