As part of the London 2012 festival, New York’s YesYesNo collective will cover the 2,000-year-old Hadrian’s Wall in balloons, making it the world’s longest work of art.
More from The Independent:
“Connecting Light” will suspend hundreds of white weather balloons above the 73-mile wall, which snakes across hill and dale in northern England just south of the Scottish border.
The balloons will be fitted with lights and networked so they can communicate with one another. Viewers will be able to submit short messages which will be transformed into pulses of colored light that pass along the wall in patterns reminiscent of Morse Code.
The project will be on view Aug. 31 and Sept. 1.
