The puzzle wasn't publicized, but an equation at about 2:23 in the video still attracted the attention of one Sylvain Zimmer. Along with "other geeks at Jamendo," (Zimmer is CTO) he figured out that the puzzle turned into an URL, goo.gl/speedanddestroy. Entering that into his browser, he was awarded with a form telling him that he was the “first to figure out our MENSA-certified puzzle” and would receive a Cr-48 netbook. The only possible obstacle is that the prize is supposed to go to a U.S. resident, which Zimmer is not.
Google hasn't been shy about hiding puzzles in its Doodles before. Of course, those didn't come with a prize.
