“Want to pretend you don’t have a TV? Get the Groove Tube, a low-tech way to turn a high-tech TV into a light sculpture. Designed by Seattle artist Matt Griesey, it’s a translucent box made of paper and plastic with a grid of opaque dividers that attaches to the screen with suction cups. When the TV (or computer) is on, the Groove Tube averages the picture pixels and creates an ever-changing display of colors in each square. Just turn down the sound and turn up the stereo.”
