ever since it was built by the Romans in the second century A.D. This 73-mile long structure was once the northernmost limit of the Roman Empire.
As part of the London 2012 Festival, the New York-based artists' collective YesYesNo will light up the entire length with a series of tethered balloons lit by internal LED lights to create a line of pulsating colors. The project, called Connecting Light, aims to transform this protective border into a line of communication.
The lights will change color to respond to messages sent across the wall. Go to the website to write your own and it may be picked to be part of this interesting project. They're looking for messages about connectivity across borders, are pretty much anything positive. Check out their blog to see how this massive art project is shaping up.Via http://www.gadling.com/2012/08/24/hadrians-wall-to-be-turned-into-worlds-longest-work-of-art/
