A visual display device for displaying a three-dimensional replica of a geographic region. The visual display device preferably includes a transparent enclosure having an interior space. A three-dimensional replica of a geographic region is preferably positioned at least partially within the interior space of the enclosure so as to be viewable through the enclosure. In a preferred aspect of the present invention the three-dimensional replica of a geographic region comprises surface features proportionally corresponding to topographical data indicative of the three-dimensional topography of the geographic region. Also, in a preferred aspect of the present invention the interior space of the enclosure is at least partially filled with a fluid. Optionally, the interior space of the enclosure may include dispersible media capable of being at least partially dispersed throughout the fluid. In another aspect of the present invention, a method for forming a visual display device is provided. Generally, the method includes the steps of providing a transparent enclosure having an interior space, using information comprising data indicative of the three-dimensional topography a geographic region to fabricate a three-dimensional replica of a geographic region, positioning the three-dimensional replica of a geographic region at least partially within the interior space of the enclosure, and filling the interior space of the enclosure with a fluid.
