Clever physical multi-party access control

found on Izismile

It's actually pretty neat that 6 different people with 6 different keys can each open this gate, and if something happens you can tell who's lock was opened. Now, of course I could imagine a fancy single lock that might be able to accomplish the same thing (more or less), but this is extendable to an arbitrarily large number.
