On a sunny Friday afternoon, Chinese artist Huang Rui opened his black-and-white umbrella at 40th and Walnut.
During the next 64 minutes, 63 others picked up umbrellas and joined him in the performance-art piece. Soon, the 64 handmade umbrellas, each emblazoned with a Chinese character and its English translation, filled a stretch of sidewalk a block long.
Huang's piece, I-Ching, takes its name from the ancient Chinese book of divination that contains 64 hexagrams used to predict the future.
I-Ching is part of a monthlong exhibition by Huang and fellow Chinese artist Ko Siu Lan organized by the Slought Foundation, a nonprofit contemporary art space, and the University of Pennsylvania.
