Microsoft Azure CTO Mark Russinovich used Claude to build a gloriously impractical setup that runs Doom in the background and [1]pastes each rendered frame into Microsoft Paint through the Windows clipboard . The project is referred to as "DoomPaint" or "MS Paint Doom" [2]on GitHub . The Register reports:

> To be clear, Microsoft Paint isn't doing anything other than serving as a place to paste from the game. [...] [3]ViZDoom runs the Doom .wad file and renders it headlessly. Each frame is passed through the Windows clipboard and pasted onto Paint's canvas. A low-level keyboard hook captures and swallows game inputs while Paint is in the foreground, and sound effects come from the game engine.

> A glance at the code shows Russinovich was more than happy to use Claude to whip it up. In a [4]LinkedIn post , he said: "I've been using Fable 5 on serious research projects and find it a noticeable improvement over Opus 4.8." Using Microsoft Paint as a display for Doom is not, however, a serious research project, as Russinovich acknowledged. "I've also been having fun with it on frivolous ones," he added, so here we are.

"Paint renders the game but does not compute it," said Russinovich. "Paint computes nothing. Paint has never computed anything. That's the joke."
