Under Scan is a public art installation based on self-representation, commissioned by East Midlands Development Agency, UK. Thousands of “video portraits” taken in Derby, Leicester, Lincoln, Northampton and Nottingham were projected on to the ground; at first, the portraits are not visible because the space is flooded by white light coming from a high-powered projector. As people walk around the area, their shadows are cast on the ground, revealing the video-portraits in short sequences. These sequences begin with the subjects in a still position, turned away from the camera. As they appear within the cast shadows, their bodies move and their heads turn to look straight at the pedestrian, establishing eye contact. When a person’s shadow moves away from the portrait, the portrait reacts by turning away and becoming dormant, eventually disappearing altogether.
