The Colors of Music

Have you ever thought to yourself, “This song reminds me of purple velvet”, “I wish this sounded more pink!” or “so, what does yellow sound like?” You tell your friends, only to be met with blank stares. Nobody knows what you’re talking about. If you’ve experienced this, you are not alone.

Galaxy Show

Lights in these kind of displays are connected to special controllers to allow them to be remotely controlled. The controllers communicate with a central unit, usually a computer, which coordinates the entire display.

The computer uses special software to run the display. This software plays a pre-programmed sequence to turn the lights on and off at set times.
