Fascinating. I think the preparation of the presentation, and the way it appears in the web page is almost as interesting. Udall calls this screencasting, and has this to say about it:

A year later it’s clear that my instincts weren’t leading me astray. I’m now using screencasts — that is, narrated movies of software in action — to showcase application tips, capture and publish product demonstrations, and even make short documentaries. And I’m seeing others around the Net starting to do the same. Now’s a good time to explain why I think this mode of communication matters and will flourish.
