So I went to the Standard Bank Gallery the other day to see an exhibition of French art featuring the human body. The art was marvellous, but the experience was a little surreal. On the floor in front of each canvas was a rectangle marked off with electrical tape. Crossing the tape set off a motion detector which triggered an alarm. For some reason, people just didn’t seem to understand this, and my entire visit to the gallery was accompanied by the sound of alarms going off.
