X-Ray Scanner a great entertainment app to trick your friends. You can scan the following objects: left hand, right hand, left foot and right foot. We'll add more object in future app updates.
There are two scan modes: above the object and in front of the object.
Above the object mode - the object you're scanning should be positioned below your phone (hold your phone parallel to the ground).
In front of the object mode - the object should be in front of your phone (hold your phone in front of your face, in standing position).
Just tilt your phone up/down or left/right to go over the "scanned object".
Note: This app is not a real x-ray scanner and doesn't use your camera. It uses your phone's accelerometer to move the image.
