A series of interactive giant LED balloons are going to illuminate the entire length of Hadrian's Wall as part of celebrations for the London 2012 Olympics.
Connecting Light will use tethered weather balloons lit by internal LED lights to form a line of pulsating colours along the wall.
The installation will be live from Friday 31 August to Saturday 1 September and is being designed to be viewed all over the world using digital media.
