Citadels is an ongoing project by dutch artist Matthijs Munnik, investigating the nature of flickering light and its effect on perception.
In his immersive installations, brightly-colored stroboscopic fields light out completely white spaces. On entering the installation the visitor’s field of view becomes filled with intricate patterns, geometric shapes and imaginary colors, strong hallucinations filling every inch of space.
Using carefully chosen combinations of colors and flicker frequencies, light interferes with the visual cortex of the audience. The images and patterns the audience see are completely created within their own brain.
The lights are combined with sound in mirroring frequencies and harmonics, moving in an ambisonic soundfield.
