Ever wondered what 100,000 big white balloons would look like? That's what French artist Charles Pétillon has put together to form Heartbeat, his first public art installation, which fills the South Hall of the Grade II-listed Victorian Market Building. Part of the London Design Festival, Pétillon's balloons are illuminated with a gently pulsing white light, hence the title of the work.
There will also be a pop-up gallery on the Piazza (Unit 5, Royal Opera House Arcade), where photographs of Pétillon's previous balloon work Invasions will be shown.
