My friend and colleague Olé Qvist Sorenson presented at a recent TEDx conference in Copenhagen. His video is wonderful. It's a simple, inviting, clear demonstration of why visualizing in groups is so much fun and so helpful. Enjoy a look. Olé's company Bigger Picture, regularly creates large-scale visualization for clients, as well as white board animation movies and many other visualizations. He's been a very inspirational example in a growing, world-wide network of visual pratitioners.
