After the conferences we decided to go to the Museum of Modern Art. There is an exhibit there by Cai Guo-Qiang. This man is the one who created the firework display for the Beijing Olympics. His medium for art is gunpowder.
This is in front of the museum. Each of these rocks has been shipped over from Quanzhou, the artist's home town. They are inscribed with verses from the Koran - the same verses that are found on many tombstones in Quanzhou. Apparently there is a large Muslim population there.
We saw videos of how he does his artwork. He lays stencils on paper, then sprinkles the gunpowder on, puts a piece of weighted cardboard on top and then lights the gunpowder. This leaves black ash on the paper.
