The Groovetube
If there’s nothing interesting to watch on television, you can turn it into an amazing disco light show. The Groovetube is simply a translucent plastic box that suction cups to the screen of your television. It has a grid of dividers inside it that diffuse the colors from your T.V. producing an amazing colorful abstraction of anything you watch. It’s probably the best thing to happen to television since the remote.
