Draw on walls with a laser pointer
Laser Graffiti is an open-source, browser-based application that lets you draw on walls using a laser pointer, a webcam, and a projector. It solves the complexity of traditional interactive projection setups by running entirely in the browser with zero installation required, translating laser movements into digital strokes in real time.
The software is designed for anyone looking to create interactive light art, play projection-mapped games like tic-tac-toe, or experiment with digital graffiti using household hardware like a laptop, a webcam, and a standard laser pointer.
