Studio Project 2026

A real-time audio-reactive installation by ØJE, built around synchronised lasers and DMX-controlled LED tubes, first presented at Blank during its 8-year anniversary.

Challenge

A system where lasers and LED tubes behave as one synchronised instrument.

Array was developed as an exploration of light as a physical and programmable structure. The installation had to react to sound in real time, translate laser movement into LED behaviour, and create a precise relationship between beam direction, pixel activation and rhythm.

Solution

A custom TouchDesigner-based control system that synchronises laser mapping, DMX-controlled LED tubes and audio-reactive parameters in real time.

When a laser beam reaches the end of a tube, TouchDesigner triggers illumination inside the LED structure — either as a single pixel, a segment, or the full tube. Light then travels through the tube as a controlled chain reaction, moving from pixel to pixel.

Lasers placed on opposite sides of the installation create two complementary behaviours: one side writes light into the structure, while the other removes it.

Details

High-intensity laser beams and DMX-controlled LED tubes arranged as a precise geometric structure.

The installation operates as a real-time audio-reactive system. Sound input affects the behaviour of the lasers and the LED tubes, allowing the structure to pulse, shift and reorganise in relation to the music.

A key part of the project is the synchronization layer developed in TouchDesigner. It connects audio analysis, laser mapping and DMX output into a single control environment. This makes the installation perform as one system rather than a set of independent devices.

Array — LED tubes and laser beams at Blank

The laser does not only illuminate the room. It becomes a data source for the LED behaviour. Its direction, position and timing are translated into pixel activation inside the tubes — a controlled relationship between beam and surface, movement and response, signal and material.

Array is part of ØJE Studio's ongoing research into real-time show systems, where light, lasers, sound and control logic are designed as one integrated environment.
