Web of Stories: Donald Knuth. 97 video clips (and transcripts) of an interview with the computer scientist. The link is to a story about how Knuth implemented a tic-tac-toe program while learning computers.
Web of Stories has many more with other interesting people. They're still in "beta," but the idea seems to be that they'll cross-index the interview clips by subject, so you can get multiple takes on, say, childhood, or war. The sum total of a single interview seems long and unedited, but it makes more sense with this feature.
