A wall of fire coloured by temperature rather than by a gradient: a turbulent heat field walks the ordering of the Planck locus, so cool ragged edges go deep red and only the hottest cores reach white. Bass is fuel; the air above refracts what is behind it.
Drawn with: a WebGL2 shader.
Reacts to and looks like: gpu, webgl2 and fire.
Family: Visualiser.
