This video shows the first beta version of TwittARound – an augmented reality Twitter viewer on the iPhone 3Gs. It shows live tweets around your location on the horizon. Because of the video see-through effect you see where the tweet comes from and how far away it is.
The app does something similar as layar(.com) -- launched in Amsterdam (NL) June 17th --, a phone interface that puts a content layer over the phone camera's videoscreen to locate the nearest toilet, bar, supermarket, bank and other search categories.
