It offers historical videos of the parade, a map of the parade with details and explanatory articles about each detail, etc. Going to the front page will bring you to an intro video:

The map is quite interesting, it has veteran accounts, war finds, a "key battles" mode with short information about each battle:

Albeit the videos, which include many interviews with veterans, are lacking English subtitles... Still, it is a huge effort and the ease of accessing information about battles, historic events and such is laudable, as is the sheer amount of information collected and presented.
The Victory Parade website is a bit different from the other, older awesome project of an interactive war map with veteran accounts, etc.:

Also, during the last year the photo project http://www.1418.ru quietly died, which is a huge shame, because it had one of the most extensive Great Patriotic War photo archives on the internet.
