  • Patent number: 5873762
    Abstract: A playing structure in one embodiment comprises a plurality of playing structure modules arranged in an array. Each of the playing structure modules includes a re-orientatable top having at least two major sides, each of the at least two major sides constituting a playing surface. The playing surface on each major side of the re-orientatable top depicts a different scene. A support frame supports the re-orientatable top above the surface on which the support frame is located in a manner such that one of the playing surfaces is upwardly presented. The re-orientatable tops of the playing structure modules in the array are first arrangeable such that the scene over the upwardly presented playing surfaces of adjacent playing structure modules is continuous and visually fluid.

  • Patent number: 5417603
    Abstract: A playing structure includes a plurality of playing structure modules connectable together to form an array having a generally continuous, visually fluid, three-dimensional playing surface. Each playing structure module has a reversible top to allow the topography of the playing surface to be changed. The top of each playing structure module has a different three-dimensional topography on either side thereof. Each playing structure module may have a different or the same top. The playing surfaces have a coloured landscape painted thereon to depict lakes, countrysides, roadways etc. and the like. The topography of the playing surfaces and the painted landscapes are designed so that the certain symmetries exist.
