The Civil War in Four Minutes

I saw the video below on Mike's Civil War Herald and found it quite moving. It's a time-lapse map of the American Civil War. In four minutes (at a rate of one week per second), it shows the major battles fought, the exchange of territory between the Union and Confederate forces, and the tremendous casualties suffered by both sides as the war progressed. It features "Ashokan Farewell", the classic song written by Jay Ungar and made famous in Ken Burns' The Civil War. The animation, which may not stay on YouTube much longer (according to the person who posted it), was actually made for the Abraham Lincoln Presidential Library and Museum. If it's pulled, you'll have to travel to Springfield, Illinois to see it, so enjoy it while you can...
