I Viewed Chameleon whilst I was in Brighton. In the gallery there was about 8 different faces spread throughout the room on projectors.
The concept of the idea was that the person on the screen copied your moods and emotions so if I was sad the person on screen would do an impression of how I feel and look.
The craft involved was using projector screens hanging around the room with a sensor on the side so it could help the person on screen copy your mood and react in the correct way.
