       | According to saltwater fish... What about all of the freshwater
       | fish?

       | Cool map though!

         | connection to each other.

         | interesting perspective of how humans also lack the ability to

         | perceive and accept it.

           | swim up and down.

       | Seems the landmasses are indeed housing off all that spilled
       | water.
       | 
       | Humor aside, the first thing it reminded me of is the Quincunx
       | projection. There all the landmass is at the centre and is housed
       | off by the oceans. And you can tile Euclidean space with it.
