This sink concept allows you to go from hot to cold with the roll of a ball, and there's no need for labels, as colored lights let you know the temperature of the water.

As you move the ball from hot to cold, the colors adjust from red to blue.

But then you have to dig around in too hot water to move the little ball...
That is really cool looking! Doesn't seem that practical, but it is a neat idea.
