2009 Oscars interactive photo hunt game on Youtube created by Joe Sabia from Boing Boing. Music by Thorsten Rock.

“There are 30 levels to the game, recapping all the big nominees for the oscars. 64 videos in all. i made use of youtube’s annotations… thought you would enjoy.” The subject matter may or may not be something that interests you, but I loved this clever and effective use of a mass-market web service feature (annotations) for a purpose other than the one for which that feature was originally developed.
