Acrossair has created a new augmented reality iPhone app that blows my mind. The Nearest Tube app for iPhones finds the closest London Tube stop to your location, tells you how far away it is using the internal compass, GPS and video camera of the iPhone.

The Acrossair Nearest Tube app for iPhone is still pending approval from Apple, but if you watch the video you’ll see why my mind is blown, and why the minds at Apple are sure to follow.
