An ordinary music box only plays a single song. The Muro Box can play any song. It uses computer-controlled wheels to flick its metal forks and can be programmed using a mobile app or a MIDI device. It has a 40-note chromatic scale, and more than 50,000 songs in a downloadable library. They also make a less-expensive N20 model with 20 notes.
Awesome Music Boxes
The sound of popping bubble wrap might be music to your ears, but Simone Giertz and her friends came up with a way to turn those pops into actual music. The machine she built uses a spinning drum and rubber feet to squish the bubbles and harnesses the air they release to play a pan flute. Zamfir, eat your heart out!
