Sculptural Staircase - The most magnificent stairways often look more like works of art, such as this serpentine piece that coils as it rises. Building these stairs combined the skills of various artisans who work with wood, metal, and drywall.
LED ribbons integrated into stairs. Late at night, the stairs can be lit (and safe) without ruining your night vision with bright overhead lights. Would also be a great way to really highlight a gorgeous staircase. @ Home Renovation Ideas
