Since it’s our favorite holiday of the year, you’ll have to pardon us if the Halloween-themed coverage is a bit excessive, but then again, who cares and shame on you if you do. Anyways, here’s a possible contender for some sort of top Halloween costume prize that comes to us from BBH NY’s Brian Moore and creative partner, Mark Svartz. The “interactive costume” pays homage to Google Street View and has been renamed, appropriately enough, Google Street Boo. Moore and Svartz’s creation, which comes complete with map tracker and live streaming video that doubles as “street view,” will be represented tonight as the pair’s streaming live from NYC’s massive Halloween parade in Greenwich Village. Check out a “how they did it” clip after the jump.
