[Editor's note: Continuing my theme of traffic flow visualization (1 | 2), here's a video by FlightSuite, NHAW, Technorama, and NASA showing animated world flight patterns in a 24 hour period as colored yellow dots traveling from city to city. I'd tell you more but I can't dig up any other information about this visualization. Tufte has a neat section on this topic. Thanks Seba!]
