My team and I developed a AR Graffiti app allowing the user to spray virtual graffiti onto a horizontal plane. The app renders many points on an identified plane and daws a line connecting the points. Further, the app uses GPS data to render graffiti sprayed by other people. A feature that we are unable to add is a hierarchy of graffiti from different time periods. The app allows for people to communicate and express their feelings and beliefs in a way that is legal and easy.
