I think this is a great example of how video changes the way that we can describe a complex and conceptual idea, in this case, the evolution of the Web. It sounds so simple, but that's what excites me so - video is not text, it's a format that provides completely new opportunities for us to communicate on the Web.
This wonderfully produced video is by Michael Wesch, Assistant professor of Cultural Anthropology, Kansas State University. It's a tad too geeky in my opinion, but still a nice piece.
