challenge
Array was developed as an exploration of light as a physical and programmable structure. The challenge was to create a system where lasers and LED tubes would behave as one synchronised instrument. 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
ØJE developed a custom TouchDesigner-based control system for Array. The system 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
Array is composed of 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.
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.
This creates 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.
