Here is a half-hour recording of a talk I gave this year at Shift camp on the year's theme of Dream. (Actually, it was the American Dream, but I went for the dream part.) I had given another version of the same talk a few weeks earlier at Boom in Portugal, but this one, which also had the feature of being recorded, was better.
Unfortunately, I couldn't get the lavalier mic together so the sound quality is not great, and towards the very end a dust storm begins to occasionally drown a word or two--which is actually appropriate, as things grow a bit apocalyptic towards the end. But hey--it was Burning Man!
