Real-time visuals, driven by sound.

Lumoi turns whatever you’re playing into living, shader-driven light — reactive to every beat. A desktop instrument for seeing music, built for the second screen and the projector.

Lumoi rendering an 8-fold kaleidoscopic visual from live audio

What it does

An instrument for seeing music.

Driven by your audio

Every pixel reacts to the live signal — any source, any app — via system loopback. No setup beyond pressing play.
A palette of modes

Flow fields, tunnels, attractors, Chladni plates, fractals and more — each a GPU shader, crossfading into the next.
Kaleidoscopic symmetry

4-, 6-, and 8-fold mirrors, Droste spirals, and hex tilings turn motion into mandalas in real time.
Color with intent

Curated palettes — Aurora, Viridis, Twilight, Mono — mapped to spectrum and energy, not slapped on top.
60fps, fullscreen

WebGL2 tuned for a steady 60fps at 1080p on integrated graphics, with headroom for 4K on a real GPU.
Locks to your set

Optional MIDI clock from Ableton gives sample-accurate beat phase; without it, Lumoi tracks the beat from the audio itself.

The instrument

A control room for light.

A live readout of tempo, waveform and spectrum on one side; modes, palettes, symmetry and fine parameters on the other. Tweak while it plays — or let Drift roam the look on its own.

The Lumoi desktop app: a HUD with tempo, waveform and spectrum; the live visual; and a controls panel with modes, palettes and symmetry

Range

One signal, endless looks.

Eleven visual modes, each built on a real physical or mathematical idea — fold in a palette and a symmetry and no two moments repeat.

01
Tide

The room, breathing.

A slow tidal wash of color that rises and recedes with the music — the calmest corner of the set, where light just breathes.
02
Lissajous

The signal, drawn in light.

Left and right channels traced against each other on a luminous scope, each figure burning a glowing trail into the dark: the raw shape of stereo, made visible.
03
Tunnel

Falling forward, forever.

An endless fluted corridor twisting toward a vanishing point, its grooved walls rippling as every beat punches a bright ring that races away into the depths.
04
Current

Sound as weather.

Thousands of particles adrift on an invisible curl of wind, the music bending the flow into eddies, streams and slow vortices that never cross and never quite settle.
05
Aura

A quarter-million points of light.

262,144 particles streaming in sheets and curtains like the aurora, folding and rebraiding with every shift in the sound.
06
Chladni

What the note looks like.

Standing waves on a vibrating plate, brightness gathering along the silent lines — sharp, symmetric cymatic figures that snap into new geometry as the pitch moves.
07
Attractor

Order on the edge of chaos.

A single point chased through a strange attractor, leaving a luminous filigree of trajectories; nudge its bifurcation with the spectrum and the whole form blooms, splits and reforms.
08
Fractal

Infinity, folded.

A kaleidoscopic fractal folded into itself again and again — dense golden architecture, the same at every scale: self-similar light, all the way down.
09
Neural

A machine's daydream.

An untrained neural network evaluated at every pixel, conjuring smooth, organic, faintly alien fields — color that feels grown rather than drawn.
10
Quantum

Interference, set in motion.

Quantum-inspired wave interference — shimmering fringes that ripple and fold, mirrored by symmetry into slow, breathing mandalas.
11
Strata

Images, in layers of light.

A stack of images set adrift — scaling, recolored and dissolved into one another — collages that are never quite the same twice, lit and bent by the sound.
