Sinusoidal Noise is a modular light installation that uses random oscillating patterns to create a larger sense of movement. The work comprises 98 pixels each of which fades on and off at a unique frequency. These slow, detuned oscillations create the illusion of shapes emerging, where light appears to pass between pixels as they move through different phases. At each instant, the emergent pattern is a unique snapshot of a chaos of sine waves. Each image quickly merges into the next; much like we tend to look for familiar shapes in clouds, visitors find themselves imagining relatable forms and observing unexpected transformations across the work.
The light pixels have no surface; they are rounded vessels that fill up with light bouncing uniformly on the internal walls. The visitor is unable to see any source of light, edges or depth within the pixels. When the light fades out, the pixel disappears as the eyes look into an empty space. This creates a soft and ethereal quality of light that moves gently over the surface of the piece.
Sinusoidal Noise is a project by Kai Lab. It was initially designed and built in 2020 by Sean Malikides, Marguerite Tricaud and Ruby Dixon. It was exhibited in 2022 at Espacio Gallery for Kai Lab's solo exhibition Phases.
