Every day, 450,000 people log on to TED.com. But where are they located? And what are they watching—our newest offerings or our classic talks? In the spirit of visual data artists like Hans Rosling and David McCandless, TED web engineer Alex Dean created a map of the United States which shows when and where TEDTalks were viewed on September 14th. A blue dot demarks those people watching a talk from 2012 and red and orange dots shows those watching our still-beloved oldies.  Above, watch a clip of his map in action. It shows that, yes, there are quite a few people tuning in for talks at 2am. And during daylight hours, marvel at how fireworks seem to appear over many cities.

Alex has open-sourced the code behind the map, so you can see how it was created and even make your own moving maps based on whatever data you like.
