There is something downright masculine about upshifting.The feeling of power as a car kicks into gear and takes off. But what if you could get the same feeling when you brush your teeth?

I'm sure that is part of the inspiration behind designer Shen Di's "+shifter" faucet concept. However, the true purpose behind the design is a unique method of conserving water. You see, the faucet regulates the water flow from low to high as the gears progress upward.

The concept certainly looks interesting, but there is one major problem: how do you control the temperature? [Yanko via DVICE]
