I'm at Interactive Screen 4.0 at the Banff New Media Institute. If I were a more dutiful blogger, I'd cover the workshops in real time... but I'm having too much fun listening and scribbling on paper to type as I go along. More impressions and lots of links later.
If you really want the moment-by-moment experience, there is a live audio feed of the precedings online, hosted by Horizon Zero, a monthly new media site with great content. (Look for the "listen live" link in the right-hand column.)
