On Earth, the Coriolis effect makes the Focault pendulum change its plane of motion, as seen by an observer standing next to it. Not on the equator; with a period equal to the period of rotation of the Earth if set on one of the poles.
Now, imagine a pendulum set to swing in the plane which contains the axis of rotation of the habitat - ie. you stand looking down the spin axis and set the pendulum swinging away from and towards you. As the pendulum descends, it will feel a Coriolis effect that pushes it at right angles from its direction of motion. As it ascends, it will be pushed the other way. It would, seen from above, trace not a line but a figure eight.
Set it swinging around an axis parallel to the spin axis of the hab, and you won't notice a thing unless you measure very accurately the pendulum's speed at every point in the arc that it traces.

Just rising swiftly from a chair might make you fall over or stagger a step or two, if you were in a small hab and your reflexes were still unused to Coriolis. A way to distinguish greenhorns and cheekakos from old spacers, perhaps. :-) Or a way for a scheming, dirty pig to "accidentally" fall into the lap of the woman sitting next to him.
