An arrangement of stones is pictured at Daranak falls in Tanay, Rizal province, east of Manila after a rock balancing performance Sept 5, 2011. Rock balancing is a performance art which involves arranging natural stones usually found on location, in gravity-defying arrangements without the need of any additional tools.
