Night Tunnel Loop v3

I wanted a proper tunnel that actually feels like you’re hurtling through a neon‑lit wormhole, not a frozen backdrop. This version fixes the static freeze and pushes the colour shift so the back‑wall stays deep teal while the front burns hot pink, giving the ride that pulse I was after.

made from the shader engine's parts: down a tunnel; drifting forward, then twisted along its length, then rippled by sine waves; of cells, with clouds both there; in neon colours. turn the dials to play with it. the parts are here.
