Kcymaerxthaere is a "parallel universe that intersects with much of our linear Earth, but with different stories, creatures, peoples, even laws of physics and qualities of existence." It has been likened to a novel with every page in a different place.
What makes the Kcymaerxthaere project particularly interesting is that the installation artist behind the project installs informative markers and historical sites at the locations in our world that connect to his world, creating real world intersections with his imagined universe. Kcymaerxthaere's website catalogues sites around the world, though the world he maps isn't one we can interface with.
The Víddaflakk, or Interdimensional Hopscotch, plaque tells the story of woman named Eliala Mei-Ning, who saved a child known throughout the parallel world as the Boy from the Sea. Six pairs of stones tell you the story of Eliala, a singer whose voice was too beautiful to be concealed, and how she was the sole witness to a murder. The guilty parties chased her relentlessly, and she would try to hide, but eventually she would need to sing. And since her voice was the most beautiful one in the world, people would instantly know it could only be her, and inevitably the bad guys would hear of her whereabouts. Knowing she had to sing, Eliala accepted her fate, traveling the world one step ahead of the Puhnee, the thugs that were chasing her.
The other plaques that tell pieces of Eliala's story are installed in Armenia, Singapore, Japan, and Spain, as well as Lithuania and Wyoming.
