Wikitude - AR Travel Guide
Be prepared to be amazed!
Wikitude, a mobile travel guide for Android phones based on location-based Wikipedia content, allows users to view 350,000 world-wide points of interest on your phone.
However, the truly compelling feature is the augmented reality cam view. Just watch this video:
Using the AR view users can use their phone to look at the world around them and see the points of interest displayed as an overlay mapped on the phone's screen.
I told you that you would be amazed.
