This is the Flower Faucet created by Italian designer Davide Vercelli for Hego Water Design.  The Flower Faucet sits on a washbasin like a regular faucet and is made entirely from glass.  The structure allows flowers to be added to the vase, making the tap totally customizable.

When the faucet is turned on, water floods into the vase from the base filling the vase to the top. As the water level reaches the top, water flows out of the spout into the washbasin.

This is such a exquisite design, combining functionality with beauty.
