Artists don’t come much more suited to Optical Sound than Mariska de Groot. Exploring the ways in which visual instruments such as projectors create organic sounds, Mariska’s performances feature various hand-made machines that openly reveal how they function.

For this particular show, light is projected through spinning wheels which have perforated patterns cut into them. Light filters through the wheels and is picked up by optical sensors and converted into audible frequencies. The beams of light and sound projected into the surrounding space are in a continuously changing composition, flooding over anything in their way.
