Anamorphosis is an artistic technique that requires the viewer to use a specific perspective to see an image correctly. It was pioneered by Leonardo da Vinci over 500 years ago. He drew a smiley face that could only be seen properly when viewed in a mirror.
I have never seen this done with a sculpture! Very, very cool.
