Gikii 2 was a big success on Wednesday. Thanks to all who made it such an interesting day. The presentations are available online. I didn't use PowerPoint slides this time (I rarely do any more, partly for reasons explained much better by Edward Tufte, though some of the presenters showed how it can be a great aid to communication when used effectively) but the paper of my short talk is here.
Update: The entertaining Fernando Barrio has posted his thoughts on the conference.
