The video I really wanted to see was "this" on 9/11. I wonder if it looked similar to what happens if you 'interrupt' a stream of ants and the 'panic' sets in.
Those interested should get hold of a copy of episode 1 of BBC's 'Britain from Above', it's a whole show visualizing everything from airtraffic to mobile phone usage.
Interestingly, the pattern of busy areas correlate with the world cities from which my website get the most traffic. It's a website about science and programming.
The rest of the world (mostly Africa and some parts of central Asia and north-western South America) doesn't seem to use internet much, neither abundant flights, neither perhaps population that can access those (or population at all).
