<p>A rotational device comprises a first member (6) mounted for rotation about a first axis, first drive means (16) to rotate the first member (6) about said first axis, a second member (8) mounted on the first member for rotation therewith about the first axis and for rotation thereto about a second axis extending transversely to the axis of rotation of the first member. In one embodiment of the invention, the rotational device is for use as a display device, and comprises a third member (10) mounted on the second member (8) for rotation relative thereto about a third axis. In a second embodiment of the invention, the device is for use as an amusement device, comprising seats (102), preferably constrained against full rotation about a horizontal axis, whereby a person sitting in the seat is not turned upside down. The seats may be mounted on a locomotion device (100) mounted for travelling movement on or around one of the members, or within stationary compartments provided by the second member.</p> |
