The Invisibility app is indeed magical. It takes a mediocre camera on your iPad 2 and turns it into something incredible.
The app uses the iPad's rear camera and gyroscope to display the background image on your screen, even when you move the tablet around. It's so seamless that it makes the iPad look almost invisible.
Invisibility is high on the wow factor and is the perfect app to whip out when your Android friends start teasing you about your "magical tablet." One minute with this 99¢ app should silence them for a while. [Invisibility via AllThingsD]
