It'll take 3:50 of your time to watch this from Kevin Kelly:
This interests me on several dimensions: as a mode of presentation (obviously, if EVERYthing was in this format it would get old fast... but it does focus the mind if it's novel, and the visual effects do nudge one to hear the message more clearly than if it's just spoken, or just straight text), for its content (some of his assertions are arguable --but which ones for you? And it's short enough to be an effective stimulus material for teaching, a good model), for its potential remixability (wouldn't it be FUN to have a class pick out particular segments to expand upon, annotate, produce new remixes of? What's the technology package necessary to do that?)
