Thanks for the tips!  It would really be nice if in animation mode,
the mpl windows had automatically a play/pause toggle at the very
least, so that regular users could get more functional animations
without having to wire these extra tricks.

I now see there's even a pause() call:

so it seems like it should be an easy matter of adding the button and
wire it to pause().   Perhaps one of your students could make a nice
contribution :)

Best of luck.  Having burned many hours on the ipython/matplotlib
event loop integration over the years, I don't envy you right now if
you're going to fight this little battle... But I'll happily cheer you
from the safety of the sidelines :)

Cheers,
