Positive tweets about London 2012 will light up the wheel

London Eye Twitter-driven light show launched for the Olympics

Daley Thompson has launched the world’s first social media-driven light show.

The London Eye will be lit up each night of the Olympics and the Paralympics in relation to positive or negative tweets.

EDF Energy, which sponsors the wheel, called on experts in ‘sentiment analysis’ to develop an algorithm for the effect. Real-time social sentiment tracking will split the tweets into positive and negative comments. Once filtered through the program, the percentage of positive tweets will be displayed in a light show on the London landmark.

So, if the nation’s tweets are 75 per cent positive, that evening three-quarters of the wheel will light up.

"We want to make the EDF Energy London Eye a spectacular showcase of national support for the athletes – and one that will inspire them every night of the Games," commented Thompson.

Tweeters can contribute to the light show by using #Energy2012
