Light rays are collected by the lens on the objective end. They are further refracted by the contents of the objective. Once the light reaches the mirrors it is reflected from one mirror to another. The angular arrangement of the mirrors determines the initial optical pattern, or rosette. Mirror width controls the size of the initial segments. Mirror length provides the surface area that allows the pattern to expand, creating the illusion of size. Turning the objective shifts the contents and forms a new pattern. Ambient light--- light from the sun, moon, incandescent or fluorescent bulbs, changes the visual effect without changing the pattern.   Cannot connect to the database.
