A light beam is applied to an optical disk through a first hologram and an objective lens. The container is adapted to permit stacking of shells in a common configuration similar to that used for factory loaded ammunitions. Additional obstacles include tunnels, spinning indicators determining the path of travel, vertical obstacles, rotating vehicles, rotating hidden compartments, and linearly sliding vehicles. The piston rod connects with the piston and also connects with the mast. The precipitated metal oxide particles have a maximum particle size of less than 1 micron. An antenna coupling element is associated with the three-dimensional structure and an output device can be coupled to the processor.
