ShareHare Turns a Webcam Hand Into a Shared Laser Pointer

Field notes

The presenter starts a room from a small Windows tray app and shares one URL. Participants use an ordinary browser on a laptop or phone, permit camera access, and point with a raised finger; the page says their video stays local while only a dot position and pinch flag are transmitted. Multiple pointers receive separate colors, and a pinch gesture adds a ripple highlight. The page lists Meet, Zoom, and Teams as compatible screen-sharing environments.
