I is bored and want people to talk to and should be working on my tutorial, so instead I'm wondering if anybody else is at PyCon?

And in the spirit of PyCon, the code to make the pics (using matplotlib animate didn't wanna work):

And the imagemagick foo to bash it into a gif:

convert -delay 10 -loop 0 traj*.png swirl.gif

convert swirl.gif -coalesce -layers OptimizeFrame oswirl.gif
