Imagine a few dozen people walking, running, jumping, jiggling their legs up and down, and introducing themselves to each other while competing on two teams. This was the scene at a recent Silicon Valley QS meetup hosted by IDEO. In the video below, David Fetherstonhaugh explains the fun, called The Step Exchange Game. The game was designed to mobilize people in large social groups to move around and meet each other. It was an exciting evening!
