Design outside the box. I’m way behind the times, but if you haven’t seen it this this talk by Jesse Schell from DICE 2010 is well worth half an hour. The whole talk is excellent (both delivery and content). It starts out with interesting reflections on facebook and various gaming systems, but the end — a sort of point-based-incentive systems meets augmented reality riff — is brilliant and a bit scary. http://g4tv.com/videos/44277/dice-2010-design-outside-the-box-presentation/
