Musicbox is a tangible interface supporting remote awareness through the medium of music and light. The musicbox is linked over the internet to the music and light levels surrounding a remote piano. The system communicates live music and a sense of physical movement through a lighted wooden ‘music box,’ while also providing browsable access to music previously played by the device.
