Giving visitors a new reason to be pee shy, the recently-unveiled public bathroom in Lausanne, Switzerland features completely transparent walls. But fortunately for patrons and passers-by alike, they don't stay that way. Equipped with liquid crystals, the glass uses electric tension to temporarily frost the glass at the touch of a button.
Like similar installations in an NYC Diesel store and other notorious bathrooms, the result is an immediately private sanctuary that returns to its see-through state at the touch of a "Voir" button. Check out a video below.
