The project Maâllem Experience was further developed as the interactive installation DiaPH and presented at the IRCAM festival Résonances in the Centre Pompidou in December 2002. In a collaboration with France Telecom Research and Development for its interactive interface, the installation proposed an experience of audiovisual immersion and navigation through interaction with projections on four screens via a suspended ball of light whose movements were detected by a tracking system and a sound score in 360° coordinated with the spatialized movement in the images.
