Panopticon

Panopticon is an architectural structure so that all inmates in an institution can be observed. The institutional building was designed by the English philosopher and social theorist Jeremy Bentham in the late 18th century. Obviously it would be impossible to view every room at once, but since every room can be observed, inmates wont know when they are being observed. This ensures constant good behavior because at all times, you don't know if big brother is watching you. "Bentham himself described the Panopticon as "a new mode of obtaining power of mind over mind, in a quantity hitherto without example." Elsewhere, in a letter, he described the Panopticon prison as "a mill for grinding rogues honest"".
I think it's a brilliant structure especially for prisons, although it's even more useful in hospitals, asylums, schools, and daycares. I'd like to see this structure built for a hospital so doctors and nurses can monitor all critical condition patients while they're in the ICU.
