Koolhaus Faucet is an interesting concept developed by Daniel Dobrogorsky so people can monitor their water consumption. The faucet not only lets you know how much water had been used, it also separates and gives statistics from all different water sources.

Although there has been similar designs, nothing I’ve seen more modern and futuristic, whether you think it’s over the top or not is another question. Overall a great concept that I think not only would be used by many, but also a clever way to encourage people to use less water.
