[Metalab] Laser Graffiti revival

Hiiii! I think Michi Zeltner (?) did something similar a few years back, and I think he was inspired by the Graffiti Research Lab (linked on my page). I revived Laser Graffiti and made it open source and a web app: https://laser.consti.de/ All you need is a laptop (with a camera), a projector and a laser pointer :-) -- Best, Consti
