'Vi’ is a music device that allows hearing-impaired children to experience music in a way that encompasses both tactile and visual music experience.

The device works by prompting the user to stick together its Lego-like components to create sounds, the sounds then vibrate the speaker, which in turn vibrate the ball bearings in the glass-dome top creating a visualized music experience. The speaker housing is made from thin plywood, allowing the vibrations to resonate through it inclining the user to place their hands on it to feel the music as well.
