A sketch of the multiceiver from Planet Earth. The full page containing this image was drawn in a style similar to a page from Franz Joseph's Star Fleet Technical Manual. A caption at the top left of the full page reads "PLANET EARTH - 2133 A.D." Gene Roddenberry originally wanted the multiceiver to be a 22nd-century version of Star Trek's tricorder. Note that the "visual display screen" is meant to be folded. The screen apparently bends without creasing when closed. While this might have been a difficult prop to build in the twentieth century, the concept would certainly be possible in the twenty-second century.
