GeoPartitura

The project Geopartitura points to emerging issues involving music, geography, and mobile devices like cell phones to allow the collective creation of a geo-referenced multimedia system in real time. The positioning of each device will allow the system to connect each device to the other within a radius of "discovery," creating for each connection a virtual string that vibrates and rings according to the distance between points.
