A WebGL light synthesizer. Pick a pattern, turn the four knobs — every frame is computed live on your GPU. Nothing is pre-rendered, nobody plays the same thing twice.
Hook up audio and the light listens back. Plug in a MIDI controller and the knobs become real. Flip LED mode to preview a 128×64 matrix panel.
⚠ Photosensitivity warning — this instrument displays rapidly changing light patterns that may trigger seizures in people with photosensitive epilepsy. If you experience discomfort, stop immediately.
