That's awesome. My hat goes off to the designer.
Would I use it? Sure, but I'd be nervous as hell. I used one of the public automatic cleaning toilets they have all over Paris, and the whole time, I kept thinking that the door was going to open prematurely.
I bet once inside and given the opportunity to prove that no one can see you, (I'm sure you could think of something
) it would turn out to be quite liberating.
