A Really Unusual Safe, The Band Safe
More gimmick then utilitarian, unless you wanna annoy the crap out of the burglar, the Band Safe is a puzzle. It works by placing an object in the center largest compartment from the bottom. To move the object to another drawer line up the arrows and tilt accordingly. So the most cryptic part of this safe is determining where the object is placed, such that you can lead it from compartment to compartment to retrieve it.
