This x-ray mirror exhibit completely debunks the phrase 'beauty is only skin deep.' When you stand in front of the digital mirror device, it shows you what lies beneath the skin -- blood and guts and all. University of Paris-South medical imaging researcher Xavier Maitre designed it to show what's going on in real time by using a Kinect camera. The same technology is used by medical professionals to make diagnoses.
Typically it would take hours of scans to see how your organs and insides move as you do, but Maitre's interactive version works without the scanning process. The simulative x-ray mirror guesses the gender of the person walking by and creates a generic height-matched image that moves with them.
