Transparent public restroom not for those with performance anxiety

As if you didn't have enough to do in the water closet, visitors to this restroom in Lausanne, Switzerland, have one added step: they must actually press the "voir" button to get a little privacy in this otherwise transparent structure. The walls are constructed with liquid crystal glass that becomes see through under electric tension -- which can be triggered via motion sensor, in case all motion ceases for a period of time (napping is not allowed) or if there is too much activity (partying is definitely not allowed). What do you think: Is this a stylish and innovative alternative to the ugly plastic porta-john? Or a disaster waiting to happen? Video after the break.
