The butterfly diagram of the fast Fourier transform, with the real spectrum on its wires — the algorithm that made every other adapter in this catalogue possible, drawn as it computes; the beat runs the pass through the stages, so the transform happens in time with the music it transforms.
Drawn with: a WebGL2 shader.
Reacts to and looks like: gpu, webgl2 and audio-reactive.
Family: Visualiser.
Runs in your browser. The preview above is the same program the renderer uses.
