Today's screencast traces the evolution of Wikipedia's Heavy metal umlaut page. I noticed it when both Tim Bray and David Weinberger pointed to it, but the page actually dates back to April 15, 2003.
It's a wonderfully silly topic, but my point is somewhat serious too. The 8.5-minute screencast turns the change history of this Wiki page into a movie, scrolls forward and backward along the timeline of the document, and follows the development of several motifs. Creating this animated narration of a document's evolution was technically challenging, but I think it suggests interesting possibilities.
