A recreational device with the shape of a dish or plate that can be manipulated to rotate and track over a bearing surface requiring considerable skill from the user. The dish device includes a platform that is rotatably mounted over a contact plate and a locking mechanism that allows the user to lock the rotation or allow, selectively, to rotate in one direction or the other. The platform in the preferred embodiment has substantially the same diameter as the plate member. In one of the alternate embodiments, however, the platform member has a smaller diameter and a static platform member is added to provide the user with an area that is rigidly mounted to the contact plate member.

A recreational device to be used on a bearing surface comprising a circular contact plate member having a convex lower surface shaped to the periphery of the contact member as a portion of a sphere such that the lower surface of the plate member at all times forms a single point of contact with a bearing surface on which the contact plate member rests, a platform member supportably mounted on the upper surface of the contact plate member for rotation about the central axis of the circular plate member, said platform member having an outer circular periphery of a diameter substantially the same as that of the circular contact plate member, and the upper surface of the recreational device being substantially smooth and upwardly unobstructed from the center of the device throughout the full radial extent of the platform member for placement and support of the feet of a user thereon throughout its full radial extent.
