Make your iPad 2 Transparent with ‘Invisibility’
Invisibility, a neat little app for the iPad 2, will make your device look almost invisible: the screen of the iPad 2 behaves like transparent glass, and as you move the device, the image is tweaked to accurately follow your movements.
The app is simple to use: take your iPad 2 over say a table or over the floor, take a picture with the app, set your device in the spot you just photographed, pinch, pan and rotate the image until it fits with the background, and once you start moving your device, the app will automatically adjust what’s displayed on the iPad’s screen, to match what’s actually behind the iPad.
You can even lift one corner of the iPad or swing it around, and the app will stretch the image accordingly – note that in this case, you will even be able to see the thin inside edge of the iPad, and a moving shadow, as if there were a big rectangular hole where the screen used to be.
To make the app work, the developer simply took advantage of the iPad 2′s sensors, especially its 3D gyroscope and accelerometers. Via the sensors, the app tracks how the device is moving, and updates the display accordingly to give the illusion that the iPad is hollow.
Invisibility for iPad 2 is available on the App Store, and costs 99 cents.
