Uncharged liquid crystals form random patterns to obscure the privacy glass on the GE Monogram Wine Reserve. Or, with an electrical charge, the crystals align so light can pass through and put the 57 bottles in view. Freestanding or built-in units feature unfinished cherry shelf fronts that can be stained to match existing cabinets. Opening the doors automatically illuminates the interior.
