VC uses the web as a platform to: (1) examine large bodies of previously inaccessible images; (2) compose original texts with unlimited numbers of full-color, high-resolution images; and (3) use new technology to explore unprecedented ways of analyzing and presenting images that open windows on modern history. (this is straight from their site)
After exploring this site I can only say you really need to check it out. The user interface is completely unique, it's totally interactive, and it is filled w/ multi-media videos/images throughout.
