| − | In this map, | + | In this map, Randall has plotted the world map featuring all the landmasses from both western and eastern hemispheres. But the longitudes west of the prime meridian, normally given negative values from 0° to -180°, have been made positive using the "ABS()" function that gives the {{w|absolute value}} by effectively stripping off the minus sign from any value. This results in the features on one side of the world being overlaid upon those of the other side, but reversed. |
| − | Thanks to the relative sparsity of western continents (most prominently the Americas, but also roughly half of Antarctica, the westernmost parts of Europe and Africa, the easternmost part of Siberia, and multiple Pacific islands), and the landless expanses of the Pacific, this is surprisingly not too dissimilar to an east-only fragment of a world map. Just with the reversed 'new world' lands added to the usual extents of continents of Africa and Eurasia and the somewhat familiar notable Antarctic Peninsula being | + | Thanks to the relative sparsity of western continents (most prominently the Americas, but also roughly half of Antarctica, the westernmost parts of Europe and Africa, the easternmost part of Siberia, and multiple Pacific islands), and the landless expanses of the Pacific, this is surprisingly not too dissimilar to an east-only fragment of a world map. Just with the reversed 'new world' lands added to the usual extents of continents of Africa and Eurasia and the somewhat familiar notable Antarctic Peninsula being recognisable but in an odd position (and reversed) with no sign of the {{w|Ross Sea|Ross}} and {{w|Weddel Sea}}s (as eastern-Antarctic landmass takes precedence). Most continents can be traced out, but North America overlaps so much with Asia that most of its outlines are hidden. |

| + | Some features of the real world disappear, such as the English Channel, the North American Great Lakes, and the Strait of Gibraltar. The Arabian Sea becomes a lake as South America cuts it off from the rest of the Indian Ocean (Indian-Pacific Ocean?). | ||

Putting into close proximity various locations that have (mainly) trans-Atlantic separation in reality. Some of these locations have been renamed in this projection by combining the names of newly overlapping locations. These are: | ||
