When visitors at the Expo 2010 Shanghai are in need of a little break from the typical pavilion perusing, one of the most popular non-pavilion attractions has been skin art.
Since the Expo trial days in April, Liu Xiaodong and two other artists have painted renditions of Le Zi, a mascot they created, on the arms, legs, hands and faces of more than 5,000 visitors.
