I'm building a feature length AR experience, scene by scene. A piece of theatre about perspective, and how we stopped hearing each other. And how we might fix it. And, through this platform, a piece of theatre you can experience wherever you are. This space will be updating and expanding until it eventually contains the entire piece, and more. Your support couldn't mean more than it would right now. publicvariabletheatre.org
