A proposal is afoot for a lightweight observation tower topped by inflatable, light-emitting spheres that would display information during the 2012 Olympic Games in London. The LEDs in the “Cloud,” fed by real-time information, would be viewable from all over the city. People would be able to visit the bubbles, while information about the games, local traffic, weather or news was being displayed. Various energy-saving and -collecting strategies would keep the installation carbon neutral, say the promoters. The only dark cloud on the horizon is a lack of funding.
