Claude codes an animated pixel-art world in pure TypeScript — full prompt shared

AIandDesign · x · 2026-11-02

A viral post shows Claude (Opus) generating an entire looping Halloween rainy-night pixel-art diorama using only TypeScript — no game engine, no image generators, just code rendering frames, crisp at 1080p and smooth enough to loop for hours as a cover for a 10-hour lofi video.
The original prompt is shared in full: it leans on strong warm/cold color contrast (cold rainy night vs firelight and glowing windows) and demands effects like rain, fire sparks, drifting smoke, and flickering light, plus a smooth-loop constraint.
@AIandDesign reproduced the trick, substantially expanded the prompt for more depth, published a web version, and shared the full revised prompt in the comments.
