To mark the 100th birthday of the composer, architect and multimedia artist Iannis Xenakis, students from both faculties at Bremen University of the Arts have been working on his work “Polytope de Cluny (1972)”, an early milestone in immersive digital media art.

They developed a light installation based on Xenakis’ historical project, but interpreted it in a new, digital and site-specific way. For this, 8 moving heads, 4 high-performance projectors, 12 custom-made motorized motors and various other lighting and media technology were used. At the same time, the original soundtracks were processed on a 32-channel 3D loudspeaker system and new spatial audio compositions were presented that respond to Xenakis’ ideas.

Lorenz Potthast from Xenorama was one of the supervising teachers and Xenorama supported the project with its media technology and expertise.
