The concept is to place the contents of your pockets on a scanner, and put your face on also. There's also a warning:
During the scanning process it is recommended not to open your eyes. If you feel that you can handle it and open them, DO NOT follow the light on its move! The authors of this project didn't find any side-effects on themselves. However, the authors do not bear the responsibilty for possible consequences. At your own risk.
