Here's how Stickybits work: put one of the stickers somewhere and take a photograph of the bar code with the Stickybits app, now available for iPhone and Android. You'll be able to "tag" it with photos and comments, as will anyone else who uses the Stickybits app to photograph the same bar code. There's a location tagged, too, thanks to a partnership with location software company SimpleGeo (whose co-founder Joe Stump called Stickybits "one of the more interesting and wonderfully weird products I've played with in quite awhile").
