Azure CTO Runs Doom Inside Microsoft Paint at 35 FPS

Microsoft Azure CTO Mark Russinovich released DoomPaint on GitHub. The project runs the original shareware Doom engine — not a re-implementation — using Paint as its display. Each frame is copied to the Windows clipboard and pasted into Paint's canvas as a bitmap, sustaining up to 35 fps. Sound and music are included. Full source and a planning document are available.
