MusicBox is a sound instrument that integrates an installation with interactions over the Internet. The physical installation consists of an old-fashioned music box with a crank handle, in which the pins have been replaced with LEDs and the notes with photo sensors for user interaction. Users can draw a shape and pattern on the screen with their mouse and the same pattern of LEDs lights up on the physical music box. Turning the crank handle on the LED cylinder, any sensors that detect light from the LEDs make a sound. Data submitted by users is stored in a database and shared by the online and offline music box.
