A picture in the form of a print or projected image onto a rear view screen in a suitable mounting is positioned in a vertical plane and the mounting then rotated extremely rapidly about a vertical axis exactly bisecting the picture in the plane. With this arrangement, each person in an audience surrounding the mounting over 360° can view the picture each time the viewer's line of sight is normal to the plane of the picture so that, in effect, the entire audience regardless of their position over 360° can view the single picture simultaneously.
