Having used a bevy of pro athletes to preach its "Impossible is Nothing" slogan, Adidas is now tapping the viral/UGC space, handing creative duties to the consumer by letting them create their own "Impossible Story."

Built by Glue London, the microsite is structured like a storyboard and is supported by an amalgam of 8-bit Nintendo beats and loops along with animated Playskool-style sketches. Users are first asked to upload a headshot or use one of the stick figure default heads created by Glue. After scaling, rotating and attaching your head, you can create up to five stories/moves featuring your running avatar as he or she wanders through a cityscape filled with assorted robots, trees and whatever other random object emerges. Not too far removed from NBC's Heroes, a built-in algorithm lets you type and render moves and concoct your own sports-tinged feats of fantasy like slam dunking the moon or pole vaulting tall buildings, which you can then send to a friend for a chuckle or two.

While some of the functionality and overall musical selection leave something to be desired, Adidas nonetheless has left its Kevin Garnett-signed shoeprint on the viral front.
