Faucets that are "canyons" of water flowing over "LEDs that change color as a function of water temperature so you can see when it's hot or cold." Awesome.
How does an LED cause the water to still be a different color after it's already flowed past the little bit where the LED is? Those pictures look doctored to me.
(I note that in the one where the water is purple, the *whole room* is purple)
