With over 190 million users sending around 65 million tweets per day, it's safe to assume that if you live in a major city, people are tweeting all around you. To see just how true that presumption was, Dr. Anders Johannson from the Centre for Advanced Spatial Analysis at the University of London put together this animation of all the Twitter traffic in central London over a 24-hour period

In the video, tweets are represented as red circles while retweets are seen as yellow streaks moving from the original tweeter to the retweeter's location. What'd we learn from this video? People never stop tweeting. Ever.
