Paul Farnsworth, who works with me, told me about the existence of something like this video, where someone has modelled US air traffic. Fascinating. There’s something about traffic flows I really love, something that helps me understand more about what’s happening in a given space. Inflows and outflows, frequency and pattern, time and space dimensions. I’ve added it to my VodPod to make things easier for you. [I think Paul meant me to visit a different site that hosted something similar. I will link to that as and when I get the information from him.]
