Rich Hickey left a comment on my last post with a link to the videos of his talk:

Part 1 and Part 2.

These are essentially screencasts of his slides, with audio added. I haven't watched them (I was there in person, after all) so I'm not sure if the Q&A audio was faithfully captured; check it out and let me know.

Update Michael Livshin reports the questions are not always audible, but the answers usually make up for it.
