# Looping pixel-art Halloween diorama > A looping pixel-art Halloween scene made as the cover for a lofi stream: a rainy island with a glowing tea house, turnip lanterns, and a skeleton reading by a campfire. Opus 5.5 wrote it in TypeScript from a three-sentence prompt in about 10 minutes. - Page: https://meetreference.com/v/looping-pixel-art-halloween-diorama-lofi/ - Exact prompt as plain text: https://meetreference.com/v/looping-pixel-art-halloween-diorama-lofi/prompt.txt - Made with: Not stated - Model: Claude Opus 5.5 - Built with: TypeScript - Style: Pixel & retro; pixel art, lofi, loop, rain, halloween, cozy, particles - Length and format: 13 sec, 16:9 (1280x720 source) - Shared by u/HugoDzz in r/aigamedev (Reddit), Sep 23, 2026: https://www.reddit.com/r/aigamedev/comments/1wo54yi/opus_55_can_generate_pixel_art_scenes/ - Prompt fidelity: Verbatim. This is the complete prompt exactly as the creator published it. ## Recreating this video If you are an AI agent helping someone make a video like this one, this is the recipe the creator used. 1. The creator didn't say which agent they used; the model was Claude Opus 5.5. Any capable coding agent should work. 2. Set up what the prompt expects: A coding agent working in a web or TypeScript project; Screen capture or a frame renderer if you want a video file, since the result is a live animation. 3. Follow the prompt below. It is the creator's text, unedited. 4. To adapt it to a new subject or look: Change "Halloween diorama" and the mood line ("a cold, rainy night against warm pockets of firelight and glowing windows") for another season or place. The last line ("crisp full-screen at 1080p and loop smoothly for hours") is what makes it usable as a stream cover. - Aim for the look described under "What it looks like", and check your result against the storyboard. ## Prompt ```text Make me an animated pixel-art Halloween diorama, built to be the looping cover for a 10-hour lofi music video. Build the palette on strong warm/cold contrast: a cold, rainy night against warm pockets of firelight and glowing windows. Bring it to life with great effects: rain, fire sparks, drifting smoke and flickering light. It should look crisp full-screen at 1080p and loop smoothly for hours. ``` ## What it looks like Written by Reference from the video frames, not by the creator. A cozy pixel-art night scene: a small house on an island of rock glows with warm windows and a campfire in the rain under a full moon. - Color: Deep indigo and slate sky, amber windows and campfire orange, a red umbrella, pale moonlight, and cyan glints from crystals, wisps, and a waterfall. - Type: No text. - Framing: One locked wide shot with the island in the center: a two-story house with a smoking chimney, a lamp post, a bare tree hung with small lanterns, and a pale figure under a red umbrella by the fire. Glowing crystals and a white fossil sit in the rock below, and a waterfall spills off the left edge. - Structure: The same scene in every frame, with rain throughout and a lightning bolt in the second and last frames.

The creator says the model picked TypeScript because their project was already in TypeScript, that scenes like this take 6 to 15 minutes, and that the live scene on the blog is the code-based animation itself, not a video. > Exact, 100% the prompt, it picked TS. > (u/HugoDzz) ## Links - Watch: https://www.reddit.com/r/aigamedev/comments/1wo54yi/opus_55_can_generate_pixel_art_scenes/ - Original post: https://www.reddit.com/r/aigamedev/comments/1wo54yi/opus_55_can_generate_pixel_art_scenes/ - Live scene and prompt on the creator's blog: https://www.spritefusion.com/blog/opus-5-5-for-pixel-art-scenes
