This is what happens, I guess, when artistic meets statistics.
I could watch it all day.
UPDATE: I've been in e-mail contact with Fernanda Viégas and Martin Wattenberg, the designers of this wind map, and while they are concerned (fairly naturally, I think) about the kind of bandwidth charges peering at this sort of graphical representation this could cost, they are considering making it more accessible (i.e. embeddable) for more general use.
So I'll stand by and await results. If nothing else, it's very beautiful. The developers in question have several very intriguing ways of presenting statistic in memorable, aesthetically pleasing fashions.
