The laser in a few 3D simulator by using camera and flash
The laser in a few 3D simulator using the camera and flash, to create a sense of augmented reality! Great joke: the screen displays a laser pointer, turn on the camera, flash, flashlight; put the phone on the vapor or smoke to give the impression that shines a laser 3D image with the phone's screen through the camera flash! Funny looks realistic, so you can make fun of your friends by showing them the laser on the screen in a couple or smoke! Look how your friends will believe in the existence of the hologram when you show them the laser simulator in steam or smoke!
ATTENTION! The laser in a couple of 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!
