Hidden Tap faucet flows from left to right as you go from dirty to clean

Here's one of those inventions that just makes sense. The Hidden Tap by Jelmer Moorman uses a sensor to follow your hands and dispense water. As you move your hands from left to right under the faucet, water goes from hot to cold just like a regular tap. We have no word on availability, but Hidden Tap is part of the Kunst Zonder Kapsones venture company started by Fernando H. Arias, so we have a feeling that given enough interest, this thing will be showing up in high-end contractors' bags of tricks at some point. Hit the continue link to see the thing in action, but be warned -- it's a .wmv file.

[Thanks, Fernando]
