Jonathan Harris is working on some cool, interesting, fascinating but weird stuff. This is his presentation at TED 2007 about We Are Fine and his new project Universe. You can see this on the TED site here.
Universe is now live at universe.daylife.com, and you can enter a news topic and watch it graphically associate all of the relevant stories in the media about that topic. This would be really cool for consumer products too, but sadly that doesn't exist.
The TED Talks are now available on iTunes as free video podcasts. I've been watching some older ones from 2002-2007.
