Recently I have been visiting OFFF festival ( www.offf.ws ). Every year they provide an amazing line up of speakers, and one of them this year was Paula Scher who gave a one hour presentation with a standing ovation in the end as result.
I loved diagrams representing the life cycle of a blog thread in the Op-Ed page of today’s New York Times and the ongoing "map" painting were interesting as well (India, Tsunami, Manhattan at Night, NYC Transit, Middle East and Paris).
