KYLE McDONALD and ARTURO CASTRO

Face Substitution and Scramble Suit, 2011
Face-tracking software maps a digital mesh on to your face; that mesh is skinned with the facial features of another person. As a result, your head and upper body appear on screen but your facial features are distorted. The skinned mesh aligns with the movement of your head, so the mask appears to be three dimensional.
