Could you build this?
Partial A basic webcam feed in JavaScript is easy, but robust real-time laser pointer detection and wall perspective calibration requires specific computer vision techniques.
What it would actually take: Built using OpenCV (WebAssembly or Python backend) with homography/perspective transform calibration between camera and projector/screen. The challenging part is robust real-time optical tracking of a bright laser spot under varying lighting conditions and camera exposure without latency.
