WW2 Western Theater national boundaries -- since medieval times!

[JasonPratt]

I love the hysterically tense music behind this map (a little like some of the music from X-Men First Class -- update, apparently from Inception); but it's pretty cool. Somewhat like the map I found tracking WW2's progress every day in the Western Theater, this one tracks national boundaries from 1140CE to the present day, one year at a time.

Thanks Jason.  I'd seen one like that before, but this one was new to me.
