"Le Messager" (the messager) was "developed by Catherine Ikam and Louis Fléri for IRCAM (Institut de Recherche et Coordination Acoustique/Musique) in Paris, uses a 3D digital scan of a model’s head to create an interactive virtual environment. The massive, disembodied head, enlarged to two metres and
projected on a screen, recalls the wizard’s avatar in Victor Fleming’s The Wizard of Oz (1939) and anticipates Dr. Know, the holographic fortune-teller in Steven Spielberg’s film of Stanley Kubrick’s screenplay Artificial Intelligence: AI (2000). Sensors in the installation track the motion of the audience and the Messenger uncannily responds as though it were looking at the viewer, following his or her movements with its eyes."[1]
