Balloons of the installation “Heartbeat” are seen at Covent Garden Market in London, Thursday, Aug. 27, 2015. “Heartbeat” is French artist Charles Petillon’s first public art installation and his first ever live work outside of France, uniting modern art with world-class architecture. Weaving its way through the South Hall of the Grade II listed Market Building, “Heartbeat” is created from 100,000 white balloons and stretches 54 meters in length and 12 meters in width, incorporating gentle pulsating white light to symbolize the beating of a heart and reflect the history, energy and dynamism of the district.
