Bus-Tops
Bus-Tops was a project for the 2012 Cultural Olympiad and is part of the Artists Taking The Lead project funded by Arts Council England and in collaboration with LOCOG.
Bus-Tops sees a series of 30 red LED screens situated on the roofs of bus stops in 20 London boroughs displaying art work made by both the public and established artists. The screens are powered by Beagle Boards running custom software and 3G connections to receive art content and upload sensor-based information. The installations are fed art content via the project's website where anyone can upload artwork to be considered for inclusion on a screen.
The project was scheduled to end at the end of the Olympic period, 30 September, 2012.
