Coordinated view display device

An arrangement for presenting a display, the arrangement comprising:

• an advancing device, the advancing device having a travel portion and being operable to cyclically advance the travel portion along a circular path in an advancing direction, the circular path having a radius and the travel portion moving in an angular direction relative to the circular path;
• an upstream collection group, the upstream collection group delimiting at least two sight-reducing elements supported on the travel portion of the advancing device for advancing movement thereby;
• a downstream collection group, the downstream collection group delimiting at least two sight-reducing elements supported on the travel portion of the advancing device for advancing movement thereby,
• an ingress associated with each of the upstream sight-reducing elements, each ingress delimiting a threshold through which light travels,
• a first view window associated with each of the upstream sight-reducing elements, wherein light at the first view window can be viewed by an observer located at a given angular location relative to the circular path, the first view window having a display range available at each angular position of the first view window that delimits an available angular extent within which the first view window is viewable, wherein, across a plurality of different angular positions of the display range that the display range occupies as the first view window displaces angularly during the advancing movement, observers who have a line of sight to the display range can view light at the first view window through a predetermined extent of angular displacement of the first view window,
• an ingress associated with each of the downstream sight-reducing elements, each ingress delimiting a threshold through which light travels,
• a second view window associated with each of the downstream sight-reducing elements, wherein light at the second view window can be viewed by an observer located at a given angular location relative to the circular path, the second view window having a display range available at each angular position of the second view window that delimits an available angular extent within which the second view window is viewable, wherein, across a plurality of different angular positions of the display range that the display range occupies as the second view window displaces angularly during the advancing movement, observers who have a line of sight to the display range can view light at the second view window through a predetermined extent of angular displacement of the second view window,
• the second view window associated with the downstream collection group being located downstream of a corresponding first view window associated with the upstream collection group relative to the advancing direction of the travel portion along the circular path such that, during each full cycle travel of the travel portion of the advancing device along the circular path, each second view window associated with the downstream collection group cyclically travel past a given location on the circular path before the corresponding first view window associated with the upstream collection group have traveled past the given location,

• a respective one of the at least two downstream sight-reducing elements being a lagging downstream sight-reducing element and being located relative to a forward downstream sight-reducing element of the at least two downstream sight-reducing elements such that the lagging downstream sight-reducing element, during each full cycle travel of the travel portion of the advancing device along the circular path, reduces the percentage of the display range of a corresponding one of a first and second view windows of the forward downstream sight-reducing element available within the line of sight of an observer remaining at a fixed angular location, whereupon, during each cycle of travel, the display range of the corresponding one of the first and second view window of the forward downstream sight-reducing element is available to an observer remaining at a fixed angular location such that the observer is able to cyclically view the display range of the corresponding one of the first and second view windows of the forward downstream sight-reducing element through a predetermined extent of angular displacement of the corresponding one of the first and second view windows and the lagging downstream sight-reducing element progressively reduces to zero the percentage of the display range of the corresponding one of the first and second view windows of the forward downstream sight-reducing element available to be viewed by the observer,
• at least a selected one of the one pair of the lagging upstream sight-reducing element and the lagging downstream sight-reducing element or the other pair of the forward upstream sight-reducing element and the forward downstream sight-reducing element being an operatively associated pair in a manner in which a corresponding at least one of the first and second view windows of the operatively associated pair have a predetermined orientation with one another, with the corresponding at least one of the first and second view windows of the respective one of the lagging upstream sight-reducing element or the forward upstream sight-reducing element of the operatively associated pair delimiting a reference bisector plane extending in a corresponding at least one of the first and second length direction of the corresponding at least one of the first and second view window such that one-half of the area of the corresponding at least one of the first and second view window lies on one side of the reference bisector plane and the other half of the area of the corresponding at least one of the first and second view windows lies on the opposite side of the reference bisector plane and the corresponding at least one of the first and second view windows of the respective one of the lagging downstream sight-reducing element or the forward downstream sight-reducing element of the operatively associated pair delimiting an offset bisector plane extending in the corresponding at least one of the first and second length direction of the view corresponding at least one of the first and second windows such that one-half of the area of the corresponding at least one of the first and second view windows lies on one side of the offset bisector plane and the other half of the area of the corresponding at least one of the first and second view windows lies on the opposite side of the offset bisector plane, and
