Paste Master: The discourse of disorder

An alarm goes off repeatedly as you walk around Time and Again, Penny Siopis's retrospective exhibition now on at the Wits Art Museum. Sensors detect when anyone crosses the red tape in front of the works, alerting the security guards, who are kept busy asking gallery visitors to keep behind it.It seems visitors feel compelled to draw closer and closer to the works until their faces are right up against the canvases.
