One of Frank’s works, Levitation, was the installation of a one-ton polyhedron from the ceiling of the Kunstraum Dornbirn in Austria. Ekko, located in northern Denmark, is a permanent installation of a path and two hundred wooden frames, through which viewers can walk. Accompanying both of these works are soundtracks made from the noises produced by visitors within the respective spaces and played back on loops, making the audience an integral aspect of the installations.
