Whilst I was in Brighton I went to the Farica gallery with Chameleon by Tina Gonsalves which was a weird piece of art as it was peoples faces on screens around the room copying your mood as you look in the cameras.
The concept behind this was that it interacts with the audience and the craft was that it is a video projected onto a little screen with a camera by the side of it which took 12 points of your face to decide what mood you were in and then the image on the screen would copy it.
