The installation “Catacoustic Movement” consists of four triangle-shaped objects. Catacoustics is the science of how sound echoes and reverberates in a room. Placed on wheels, the structures are mobile in the room and can thus be made to react- and function with different situations and areas within the gallery. They are also fractions of additional walls that conceals, hides, reveals, echoes and reverberates. The four triangles are inspired by sound absorbing and sound reflecting structures and materials.
