I built a laser dry-fire shooting game with Claude Code: a webcam watches your monitor and scores laser hits (open source, free)

I built ScreenPlink with Claude Code over about two weeks. It is a laser dry-fire shooting game where your monitor is the target. You shoot the screen with a laser trainer pistol, or with a laser cartridge in your own gun. A webcam sitting beside the monitor watches the screen rather than you, the app works out which pixel you hit, punches a bullet hole there, and the target falls. Nine drills, fifteen figures with scoring rings, a 17-round magazine, and two players on one screen. You can also take both halves yourself with a pistol in each hand: two lasers landing in the same camera frame are
