The full story

The maker remembered stress.exe, a freeware program that let you smash your screen with hammers, a chain-saw, a flame-thrower and termites. After reading about Reverse Engineer Anything, they tried it with Claude Opus 5.5.

Within 30 minutes they had a faithful port using the original graphics, animations and stereo sound effects. After about two hours it was available as a downloadable .dmg for macOS and as a web app styled like a Windows XP desktop. The post credits the original author, Miroslav Němeček.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count). The Claude connector only receives the search words your Claude sends it.
