Pobediteli: Soldiers of the Great War
Pobediteli: Soldiers of the Great War was a Russian Internet project created in 2005 to commemorate the 60th anniversary of the end of World War II (in the former Soviet Union, the Great Patriotic War). It involves an incredible animated and interactive map of the Eastern Front from 1941 to 1945, with popup windows appearing as the timeline progresses that include original documents, audio and transcripts from surviving veterans, and details of key military engagements. Possibly the most over-the-top interactive historical map I have ever seen. Via Kottke; thanks also to Neil Bruder.
