London Eye to gauge mood of Olympic Fans

Here's a particularly cool idea from Olympic Games sponsor EDF energy - the U.K. power company who will illuminate the London Eye during the Olympic Games and Paralympics with a light show made from Games-related tweets. The "Energy of the Nation" initiative will measure the nation’s mood using data from 10 million U.K. Twitter users. The results will be used to put on a "low carbon" light show each night at 9pm.  In short, the London Eye will be the ultimate barometer as to how much people in the Twittersphere are enjoying the games.
