Where can I find a sound sensitive color changing light box?

Question

I saw this yesterday at a music show. it was a piece of white plastic sectioned in a 2x2 grid with lights. The lights in each section of the grid changed colours depending upon the sounds in its vicinity. Kind of like an analog version of a 'visualizer.'

Your description was accurate, for sure. A device of this type is commonly called "color organ", a name originating in the 18th century to describe colorful mechanical devices that moved while playing music. In the '60s, the flower generation used the name to describe electronic devices which would modulate 3 (usually) colors of light with sound in 3 frequency ranges (bass, midrange, high). Millions of color organs have been sold since then, and many many built from kits, allowing users to create unique pieces of optical art. If you search with the term "color organ", I am sure you will find what you seek. Cheers!
