  • a light source;

    a container surrounding said light source, said container having a substantially vertical central axis and being perforated with apertures such that when said container is placed within the room, light from said light source passes through said apertures and creates a pattern of light spots on the interior surfaces of the room, said apertures being arranged such that said pattern of light spots resembles an arrangement of stars in a known stellar constellation;

    means for adjustably positioning said light source within said container to alter said pattern of light spots; and

    a stand supporting said container and having a plurality of legs of independently adjustable length such that said container can be tilted to adjustable position said pattern of light spots on the interior surfaces of the room,wherein said light source comprises a light bulb having a filament of length short enough so that said apertures are substantially as wide in shortest dimension as said filament length.
