JJ's show opened on Sept 6 and I was there to witness his performance piece called "water".  This involved the projection of several historical photos of famous Chinese political figures, including of course Chairman Mao, on a blank wall while JJ used water and a large brush to paint images on the wall.  These images faded along with the projections and were then written over or juxtaposed with each other to form a watery impression of recent Chinese history.  He used water as a motif throughout the performance, painting waves and also projecting images of waves on the wall along with the historic figures.
