Want to see that ad in 3D

It works like this. Customers view themselves on a screen through a Webcam and hold up a 2D picture. Suddenly the 2D picture pops up and consumers see themselves holding a 3D simulation of the product in the brochure on the kiosk's video feed. Sometimes it doesn't work: the 3D image will disappear if you hold the picture at a wrong angle. Still, it's an eye-grabber for a kiosk application.
