Here's some cool links i picked up from the talks:

http://www.eyeoverfishing.org/ - eye over fishing shows how fishing has damaged the sea and shows a way in which this could be corrected.

http://www.visualcomplexity.com/vc/ - A site that contains graphic approaches to displaying info.

http://www.davidberman.com/social/dogood.php - i want this book. This line says a lot - "designers will choose what their young profession will be about: inventing deceptions that encourage overconsumption -- or helping repair the world."
