I have been on a PhD looking at the role of game structures for participatory artworks. I have developed this project, that looks at how perhaps gaming principles of Mechanics and location through something called the Magic Circle can be of use to participatory artworks in public locations. This work, is a recalibration of Paper Scissors stone, with new elements, that are created through sign language, and it uses giant mech hands too, imaginative props to bring participants in. It is hoped to be meaningful, so they get a taste of a subject they can use outside of the gameplay. Would really appreciate any feedback etc, and the chance to do this again elsewhere.
