A method and a combination for assembling of an illuminator and a decorative cover made of polyhedron structure, imprinted with design motifs and/or used in restaurants and other service institutions for decoration and for commercial presentations including menus and listed service.The polyhedron cover is an incomplete structure short of at least one geometric surface or is truncated having attachment flaps around the missing or the truncated geometric surface for attachment to an illuminator base.The illuminator base includes slots to enclose the flaps, locks to attach the flaps and a rotating actuator that is used as a rotating base for the illuminator to enable the rotation of the cover around a stand or a support to review the imprinted motifs or menus around the cover.The base further includes at least one switching device and the actuator includes activator for said switching device and the illuminator is actuated by rotating and pushing or pulling the cover. The illuminator also includes remote control, includes battery operation that can be recharged, and the polyhedron cover can be designed, printed and assembled by the user from sheet material.A precut polyhedron from a sheet of a plastic or paper and other materials in a standard size for a PC printer can be keyed and supplied with pre bonding for self printing and assembling by the user.
