Renshui has designed a futuristic faucet that uses an integrated chipset to control water temperature and a touch-based interface to control water flow. As cool as that tech sounds, I'm not sure it's any better than the classic two-knob setup.

A neat touch that I wouldn't mind in future sink faucets, showers, etc: the Renshui faucet displays the exact temperature of the water, so you can easily get the water to your own perfect temperature. [Renshui via UberGizmo]
