The point of a lock is twofold (in most cases* ). First, to discourage casual/opportunistic access. Second, to make unauthorised access evident. I believe this lock meets those criteria, albeit at a minimal level - but it's purpose is to educate, rather than to directly secure.
* In specialised cases the expectation is that the lock will also take a finite amount of time to get through, which may exceed that of the door, allowing for a response to alarms, for example. In other cases a lock may be designed such that the contents would be destroyed by any action which would defeat the lock.
However, as an art piece this is impressive.
