Charcoal Ember Glow

A bed of charcoal with ash on its plates and embers glowing in every crack. Token rate is the airflow: the cracks breathe brighter, then flicker hot as the stream speeds up.

Also known as: ember glow shader, burning charcoal texture, glowing cracks animation.

Customizing this shader

  • Speed: uTps is the token rate and uTokens the running count. The standalone runner adds a natural wobble to a fixed rate, the way real streams speed up and slow down.
  • Color: set data-color on the canvas, or change uColor in the Shadertoy version. Currently previewing #ff6a2b.
  • Size: style the canvas with CSS. It renders at up to twice your screen's pixel density and stops drawing while it is off screen.
  • Reduced motion: the runner draws a single still frame for people who asked their OS for less motion.
