MusicBall vs MeloDraw

Drop in a song. Watch a machine get built to play it. MusicBall takes a piece of music and constructs a whole contraption around it — plates, curving rails, spiralling drops. Then a ball falls through the lot, and every note you hear is the ball hitting something. It's oddly hard to stop watching. EVERY SONG GETS ITS OWN MACHINE Change the song and everything changes. A gentle piece grows tall spirals the ball winds slowly down through. A fast one packs tight columns it ping-pongs between. Switch back and forth and you'll never see the same machine twice. YOU'LL START TO SEE THE MUSIC Every note has its own colour, and it keeps that colour wherever it turns up. A few minutes in and you're spotting a melody's repeats on the wall before you hear them come round again. PICK WHO PLAYS THE MELODY Hand the tune to a different part and the whole machine rebuilds around it. Or let the spotlight travel between parts as the piece goes on — the ball slides across to a new rig each time the lead changes. Or run two balls at once, side by side. EVERY HIT LANDS ON THE BEAT The ball never fakes it. It arrives exactly when the note does, every single time — so what you're watching and what you're hearing are the same thing happening. BRING YOUR OWN FAVOURITE Seven classics are built in to get you started: Canon in D, The Entertainer, Turkish March, In the Hall of the Mountain King, Für Elise, Prelude in C and Gymnopédie No. 1. After that, bring in anything you like — your file stays on your phone. FLY THE CAMERA Ride along with the ball, or take over: spin around it, pan across the machine, pinch to take in the whole thing at once. NOTHING TO SIGN UP FOR No account. No ads. No tracking, nothing collected. It works exactly the same in Airplane Mode.
