iRay turns your iPhone/iPod touch into an mobile X-Ray device to impress your friends. OK actually this application is only a mobile trick and as your device can't generate any X-radiation no one will get harmed but your friends will be still impressed. Here is how it works: You can control the movement of the X-Ray picture of a hand by slightly tilting your device using the builtin accelerometers. Now move your device above the victims hand (you can use your own hand if you want) following the picture on the screen. But remember: as for any magic trick you have to practice and you have to think of a story to sell it!
