A grid on an elastic sheet pulled by eight attractors, one per band, each with real spring and damping so it lags and overshoots. The distortion is an inverse map, so the sheet can be stretched to any extreme without ever tearing.
Drawn with: a WebGL2 shader.
Reacts to and looks like: gpu, webgl2 and psychedelic.
Family: Visualiser.
