The prompt that gets copied
Build me a simple, fun web app in Canvas that turns my webcam into a musical instrument. How it should work: when I move my hands in different parts of the camera view, it plays different notes. Left side plays low notes, right side plays high notes, and moving faster makes it louder. Show the live camera feed with soft glowing shapes where it sees movement. Sound style: [SOUND STYLE, e.g. calm piano chords] Who's playing: [WHO'S PLAYING, e.g. my kids, ages 6 and 9] Keep the notes in one musical key so it always sounds nice. Add a big start button, a volume slider and three sound presets to switch between. Use large, friendly text. Keep everything running in the browser, and don't save or send any video anywhere. If something doesn't work, explain in plain words what I should click.
Ask Gemini Canvas to build a small app that turns your webcam into an instrument. Move your hands and the app plays notes, so the whole family can jam with no gear.
