You are standing in front of ‘Red Man, Green Man’ by George Clark. This multimedia art work was originally set as a social experiment. What the spectators see is a pole on both sides of difficult crossing. On each pole you can see either a red man or a green man. George Clark activates an interaction with the spectators by adding a button to the poles.
Clark is playfully making a statement about illusion of control. The visitors think they can control the red man.
