concept video: the future of pervasive games?

If you're a fan of ubicomp street games and mobile experience design futures, check out this fun pervasive gaming concept video from HP, (officially titled "Roku's Reward", although I like to think of it as "Sign of the Sorceress" after the game). And for a good compare & contrast exercise, go back to the interesting Nokia Explore 2012 concept video that Matt Jones posted, which sketches some clever mobile/media interaction ideas.
