Fucking terrifying.

Humans did this. On purpose. Money was spent to achieve it.

The most unsettling toilet I saw was at a mall in Osaka - all four sides, floor-to-ceiling mirrors. Pooping into infinity.

If you were a fan on exhibitionism the Sapporo Tower observation decks let you take a leak in full view of the bay windows for the building, but you're 37 stories up so I guess not many people are looking.
