Plastic Swim is an AR experience to raise awareness about the toll of plastics on the environment. The player begins by overlaying a lakeside terrain over their current location through their smart phone. While interacting with the app, the viewer will find themselves in a glimmering but treacherous game, swiping through an aquatic world dense with plastic. When they have accumulated enough information about plastic consumption by interacting with illuminating debris they can resurface buoyed by the specifics of their newly acquired environmental awareness.
