Optical Machines is the performance project of video artist Rikkert Brok (b.1974) and sound designer Maarten Halmans (b.1974). Their unique approach focuses on process, improvisation and integration of image and sound. They use purpose built equipment to produce images that invoke 60s stroboscopic flicker devices – dreammachines built by Brion Gyson – closely linked to live sound. The images are generated, manipulated and mixed from light sources live on stage with projectors engineered to generate loop sequences of interfering patterns and abstract animation. Interaction between image and sound is achieved with build in sensors. The sensors provide a signal to control several (analogue) synthesizers.
 
Based in the Netherlands, both artists are associated with the Dutch EatConcrete label. Rikkert Brok develops unorthodox projectors to produce abstract moving images where the equipment is as important as the projection. His projectors are designed with an open structure allowing a view of what’s happening inside. Brok studied at the Interfaculty Image and Sound in Den Haag and graduated in 2002. He also works under the moniker Lums.
 
Maarten Halmans started making electronic music in the early 90s, becoming passionate about analogue synthesizers. He's a member of the group Mononom known for their mid 90s productions on the legendary Bunker Records sub-label Acid Planet. The have also released music on EatConcrete. Halmans is a qualified electronic engineer. He designs and builds his own analogue synthesizers and interfaces.
