Michael Gaio is a ‘world citizen’ and a creative, brilliant and talented designer and developer. We worked together to create a pioneering visual tool for systems thinking and learning. With only a few guidelines and creative suggestions from me, he quickly developed an elegant, complex, and interactive ‘World Systems Map’ that allows students to learn and explore at their own pace about the overall condition of the Earth and its many interacting systems. His demonstration project has inspired others such as the Buckminster Fuller Institute. I give Michael my highest recommendation.
