Using "analog teaching technology" from Ikea (of all places).
I am in awe of Hans Rosling. This man makes data come alive and his talks are usually beautifully scripted using animated graphs to show you how the real world changes over time. This time around he keeps it simple and all the animation is in his voice and in his face. He says that he is neither an optimist nor a pessimist - he is a "possibilitist."
