2ad, the Second International Appliance Design Conference was one of the best conferences I've been to. Small (150 people, though it seemed even smaller than that), focused (one track, carefully sequenced), brave (they scheduled a robot soccer tournament in the middle of the thing!) and smart. I was really flattered when they accepted my proposal to do a side show for their Bazaar, similar to UPA's Idea Market (which, incidentally, I--uh--was supposed to talk at later this week, but unfortunately can't be at--it looks great, though). I really like the Idea Trade Show concept behind this, and it seemed to work particularly well at 2ad. In fact, Ann Light, of Usability News, has written an excellent roundup of how it went.
I don't know if it's just my brain pattern matching, but it seemed that key ideas of two of my favorite gatherings--Burning Man and the TED conferences--were incorporated in, of all things, a corporate research lab context. Burning Man is the mother of all performance bazaars and TED is the best idea theater in the world, and 2ad managed to capture some of the magic of both. Props to the organizers. I can't wait to go next year.
