A structure (100) capable of generating a virtual polyhedral space including a plurality of walls (102, 104, 106) each having a first side edge (110, 112, 114), a second side edge (116, 118, 120) and a reflective surface. The walls are disposed adjacent each other, with the first side edge of each wall adjacent the second side edge of an adjacent wall, each wall lying in an associated one of a plurality of planes intersecting at a common apex (O), thus forming a pyramid shaped structure. The walls of the structure are arranged so as to define an interior space of the structure, with the reflective surfaces of the walls facing the interior space. Each of the walls includes a base edge (122, 124, 126), wherein the base edges of the reflective walls define a base opening of the structure so as to provide access to the interior space.
