This project maps sounds from people's everyday lives and allows the user to walk in another person's shoes, literally. Ideally people would bring their own shoes which they would map to a sound (we would have plenty available) that they felt related to themselves and then others would be able to make music, exploring what types of beats people brought. It requires significant coordination among team members to produce a synthesis that sounds good .....we're still practicing.
