California-based Hero Design, a firm that creates interactive exhibits, has created a giant-sized Lite-Brite called the Everbright. A simple twist interface allows users to turn on each lamp and change the color. They are available for purchase and I hope someone will place one in rental inventory since this would be a great event attraction.

It is super intuitive, can be used by multiple users and the units can be ganged together to make larger installations.
