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. The scene on at least one playing surface of a re-orientatable top has less than four-fold symmetry such that the scene is continuous and visually fluid over the upwardly presented playing surfaces of adjacent playing structure modules when the re-orientatable top of that at least one playing structure module is re-orientated about a bisector passing through the center of the re-orientatable top to present upwardly the other of the playing surfaces of the re-orientatable top.
