A four-dimensional cube turning in deep space: 16 corners rotated in three 4D planes and projected twice, with each of its 32 glowing edges keyed to its own frequency band, so bass thickens the near struts while the highs light the far lattice.
Drawn with: a WebGL2 shader.
Reacts to and looks like: gpu, webgl2 and 4d.
Family: Visualiser.
