Xray Prank

Xray Prank is an app that lets you turn your Android device into a x-ray machine. Well, not really, but it will make your device look like it's an x-ray machine.

From the Xray Prank interface, you can select which part of the body you want to x-ray. In reality, what you do is choose a body part and then see the x-ray image on the screen of your device. Then, thanks to the accelerometer, whenever the device moves up or down, the image will also move up or down, so if you're focusing on that part of the body, it will seem like the app really has x-ray capabilities.

Xray Prank is, as the name itself suggests, a joke app. However, it is one of the better joke apps you can find for Android.
