If you’re going to be in London for the 2012 Olympics and are planning to tweet about your experiences, it seems that not only will your tweets be shared with your followers (as expected), but there is a good chance that it will help turn the London Eye into a mood ring of sorts. The landmark will be lit up every night during the games and will have its lights reflect the overall mood/sentiment of tweeters. This is thanks to an algorithm put together by experts on “sentiment analysis” who will scan for tweets in the UK using the #Energy2012 tag, and via that algorithm, it will determine the amount of positivity. As shown in the example above, a positive energy rating of 75% will light up three quarters of the ferris wheel, while (we’re guessing) a 100% positive energy rating will light up the entire wheel, putting on a spectacular light show for all to see.
According to athlete Daley Thompson who launched this initiative, “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.”
