PICNIC07: Minimally Invasive Education through Social Play, Dr. Sugata Mitra
I've been looking forward to this one :) So obviously my battery is running low :(
Later: easily the best talk so far. Wonderfully simple, uplifting and socially important. Find out anything you can about this and the guy behind it. Thanks to Ribot Minimus for a link to his presentation at LIFT07 (which I missed).
