One of the first augmented reality apps to go live in the iPhone AppStore. Forget boring 2D transit maps! Try this amazing new application that tells people of Tokyo where their nearest subway station is via their iPhones video function.

When you load the app, holding it flat, all lines of the Tokyo subway are displayed in coloured arrows. By tilting the phone upwards, you will see the nearest stations: what direction they are in relation to your location, how many miles away they are and what lines they are on. If you continue to tilt the phone upwards, you will see stations further away, as stacked icons. Only available to Apple iPhone 3GS users.
