This is a screenshot from the National Air Traffic Controllers Association (an organization that knows how to party) real-time map of flights over North America. Except it's not actually real-time, it's delayed 5 minutes. Of course, judging from the 2005 copyright in the lower left this may have existed for awhile. But what it lacks in newness I think we can all agree is more than made up for in, uh, little white dots. Don't let Pac-Man see it!

Thanks to e, who's contemplating flying south for the winter. Smart -- I don't jive with the cold either.
