Want to find nearest Tube station? There's an app for that

One of the first augmented reality apps to go live in the iPhone AppStore is an amazing app for finding your nearest London Underground station. Acrossair have brought out a magical app that directs you to nearby Tubes in a wonderfully visual way. "By tilting the phone upwards, you will see the nearest stations: what direction they are in relation to your location, how many kilometres 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."


It's only available to Apple iPhone 3GS users and almost makes me want to get one.

Thanks to sizemore & Jon Justice for the heads up on this.

I can't even pretend to understand the technology or "the science bit" behind this. So I'll leave Engadget to explain how it came about: "With the iPhone 3GS pimping an improved camera, in built compass and GPS, we had a hunch that it wouldn't be long before someone slammed them all together and gave commuters and tourists alike a reason to smile."
