Mobility references a form of communication that has almost been consigned to oblivion: the use of a mirror and sunlight to exchange information over long distances.
A grid of one hundred white prosthetic hands actuated by stepper motors, enabling them to rotate around their own axis, are mounted on a wall. Each hand holds a small mirror. An adjacently positioned bright light source shines on this matrix, causing the turning mirrors to cast small moving light spots across the space. What initially seems like an asynchronous, chaotic pattern of movement soon reveals itself as complex, computational choreography that culminates in forming a Chinese character denoting movement and action. The work was commissioned for Expo Shanghai 2010, Pavilion for the Disabled.
