The full story

The poster asked Claude Opus 5.5 to port the Armagetron project to WebGL and deploy it with a websocket-based multiplayer backend on GenHTTP Lambda. The initial port took 1.6 million tokens, and bug fixing and multiplayer improvements took another 600,000.

They gave only user requirements, no technical details, so Claude wrote and pushed the backend alone. It uses one websocket connection per player and sends the network state at 60 Hz via protobuf. A playable link is shared in the post.

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.
