A sink is a sink, but not when it has LEDs. Then it's a Super Sink. This Hansa tap has LEDs that light up in response to the water temperature. Blue is for cold, red is for hot, and white is for plasma. The image shows them looking like blood and toilet water, respectively, but I suppose this sort of LED water UI can help those with no nerve endings in their hands.
