A apparatus for moving an object comprises a main frame (32) defining a platform (34) and an aperture (36), through which aperture (36) a spherical body (38) protrudes. The spherical body (38) includes two arrows (40,42) displayed on diametrically opposed surface portions of the body (38). In use, the apparatus (30) is adapted to rotate the spherical body (38) alternately about different axes of rotation (44,46). Rotation of the spherical body about axis (44) maintains the arrows (40,42) in a single orientation and rotation of the body (38) about the axis (46) will cause the arrows (40,42) to change orientation. By manipulating the speed of rotation of the body about the respective axes (44,46) and by alternating rotation about one axis and then the other, an audience or user viewing the spherical body (38) will be amused and intrigued by the alternating direction changes of the arrows (40,42).
