The view from a night train: town lights, poles and trackside lamps pass at their own depths, smeared by speed, over a faint reflection of the cabin. Tokens set the speed.
Also known as: train window shader, night journey background, parallax lights glsl, motion blur lights.

Unlock the standalone HTML and GLSL
Everything you see above is live. Basic and Pro include every premium piece, with the standalone HTML and GLSL ready to copy, plus Motions in Claude Code on Pro.
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 #ff9a3c.
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.
