Volunteers stand in the ocean during an art exhibit; performers demonstrate the Coopers' Dance at Marienplatz Square; participants join the annual "No Pants Subway Ride" and more.
Volunteers stand and read the morning newspaper while “waiting for the bus” at Henley Beach on Jan. 8 in Adelaide, Australia. Surrealist artist Andrew Baines recruited 100 volunteers for this human installation, meant to illustrate corporate workers enjoying nature rather than waiting in a long queue for a trip to work.
