This animation illustrates how the precession of the Foucault pendulum arises from watching motion from a non-inertial reference frame. The pendulum initially swings in a plane from the viewpoint of a playground, but appears the plane of the swings appears to rotate when viewed from the rotating reference frame (a merry-go-round) on which it rides.
