So, this is a pretty cool thing. In three and a half minutes you can watch a thousand years of European history unfold before your eyes. The one downside is that there is no timeline with a little running dude, or date-o-meter, or something to let you know where you are (when you are, said Inspector Spacetime). If you know a smattering of history here and there, you can pin it down though.
It looks like the progression of time is not completely uniform, though. If you're interested, here's a little guide for you
1066 = 0.05 (Norman conquest of England)
1204 = 0:18 (Fourth crusade sacks Constantinople)
1478 = 1:11 (Conquest of the Novgorod Republic by Ivan III)
1580 = 1:32 (Union of Spain and Portugal)
1603 = 1:37 (Unification of England and Scotland under James I)
1795 = 2:24 (Third Partition of Poland)
1812 = 2:33 (French Invasion of Russia)
1914 = 2:53 (Start of World War I)
1942 = 3:06 (Farthest German advance in WWII)
1990 = 3:15 (Reunification of Germany)
Ooh, and, as I was writing this, the creator posted another version, which is much slower, running for 11 minutes, and more zoomed in.
