We inhabit an ever changing world where everything is flowing: water, air, people, traffic, weather, satellites and U.F.O. Movement influences our lives and everything around us. Movement can be deliberate or incidental; it can be random or predictable. Help us capture how movement influences health. A neighbor walking a dog? Contaminants flowing into a river? An invasion of a new pest? Help us visualize movement as a connector between the health of human beings, animals, plants and of the environment.
