I presented Avalon yesterday at FITC, a very cool conference.  It has both creative and technical tracks and is attended by lots of people think on the edge of UI design.  For example, check out this site http://www.moock.org/ -- perhaps the only site out there with a blank homepage -- but stick around, there more here than meets the eye.

The conference has been great -- nice to work with people who are as fired up about design and philosophy as they are about code...
