To Do:

change.
Explanation:
In front, is a screen and infrared camera. Behind the screen is a computer. Behind you is reflective material. Above, is a digital projector. The camera sees your silhouette on the reflective wall, and projects it onto the front screen. The digital projector projects the scenes. And both projections are controlled by the computer.
Application:
The reflective sheet is the same material you see on highway signs. The camera is the same as in high-tech surveillance cameras. The projector system is the same as in high- definition television broadcast.
