ABSTRACT:
The invention is a viewing device suitable as a novelty item or for such other purposes as a teaching or navigational aid. It comprises a compass and in its preferred form has a 360.degree. panoramic photograph wrapped into drum form and affixed to the compass. A viewing device is also provided, so that when the person observing the photograph is facing a given compass direction, he will see essentially the same view that would be seen by another observer facing in the same compass direction at the point at which the photograph was taken. An essential part of the invention is the way the photograph is represented. If the viewing device is arranged to see the outside surface of the drum-shaped photograph, the photograph must be a mirror-image representation. If the viewing means is arranged to see the inside surface of the drum-shaped photograph, a normal representation must be used. In other versions of the invention, the photographs need not have edge-to-edge continuity. In any case, a person observing the photographs will see different representations as he or she faces in different compass directions.
