Abstract
Presented is a segmented spherical display device including at least four embodiments. The segmented spherical body of the display device may be, but need not be, transparent, is segmented in specific ways unique to different segment configurations to provide multiple flat surface portions or facets, each defined by at least two straight edges or lines of demarcation and one arcuate edge subtending the angle defined by the two straight edges, and to which or on which facets may be detachably mounted selected visual indicia or images for visual display. In two of the embodiments, the segmented spherical bodies are each segmented to provide two bodies that are halves of a sphere, that are mirror-images of one another and interengageable to form a segmented sphere. In the other two embodiments, the respective spherical bodies are each segmented to provide four quarter-sphere segment portions or bodies that are mirror-images of one another. In each embodiment, the separate mirror-image segment bodies may be interengaged to complete a sphere, with each facet provided with indicia or an image to be displayed, or each independent segment body, with indicia or images mounted on its various…
