Nearest Tube will be one of the first augmented reality app to go live in the iPhone AppStore. Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data.
No boring 2D tube maps anymore, but an amazing application that tells Londoners where their nearest tube station is via their iPhone's video function.
When you load the app, then hold your iPhone flat, all 13 lines of the London underground are displayed in colored arrows. By tilting the device upwards, you'll see the nearest stations: the direction they are in relation to your present location, how many kilometers and miles away they are and what tube lines they are on. If you continue to tilt the phone upwards, you will see stations further away, as stacked icons.
Here a video of this amazing application:

This application will only be available to iPhone 3GS users.
Acrossair, the company who has developed this application has also just finished their work on a New-York underground version and is betatesting the versions for San Francisco, Chicago, Washington DC, Paris, Tokyo, Berlin, Madrid and Barcelona.
