In a couple hologram 3D laser projection in a few using the camera and flash, to create a sense of augmented reality! Great joke: the screen displays a laser keyboard, turns on camera, flash, flashlight; put the phone on the vapor or smoke to give the impression that shines 3D laser image of a keyboard for working with a computer or other gadget!
Funny looks realistic, so you can make fun of your friends by showing them a projection of a keyboard on the screen in a couple or smoke! Look how your friends will believe in the existence of the hologram when you show them a simulation of projections in a couple or smoke!
ATTENTION! In a couple hologram 3D – a joke, simulator! The phone camera cannot project an image on any surface or steam! The phone is not a device to create a laser hologram!
