This site exists because of [a tweet](https://x.com/Tsutsui0524/status/2075523423653277725). A Japanese user posted that their father thought the Minecraft icon was a mosaic, a censored photo, so they asked an AI to remove the blur. The model, having no idea it was looking at a video game texture, confidently resolved the grass block into two bodybuilders posing in a forest, and it went pretty viral.

I wanted to see what the AI would find in the rest of the game, so I ran the same trick on the 82 blocks featured on the site. Each one steps through a de-pixelation sequence at 80%, 60%, 30%, and finally 0% pixelation, and every stage is generated from nothing but the image of the stage before it. The prompt never names the block; the only instruction is, in effect, "de-pixelate this a bit more." The model's small guesses pile up and drift from step to step, which is the whole fun. Some blocks stay boring, the AI decides stone is stone, and others end up somewhere genuinely strange.

None of this is technically hard. The part I enjoyed was making it run honestly and unattended: more than three hundred image generations, split across eight agent workers, each with its own queue of blocks and a per-block manifest tracking progress. The harness rules are strict so the illusion can't cheat. Each stage may only reference the immediately previous image, never the original texture, and every temporary filename is opaque so the block's name never leaks into the model's context. Completed blocks are skipped on restart, so the whole catalog was a matter of prompting the workers, walking away, and coming back to finished reveals.

Here's the release video:
