I may be very easy to amuse but but Spilhaus projection for compact Hausdorff space (the surface of the Earth) tickled my drying bones. 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. https://en.wikipedia.org/wiki/Peirce_quincuncial_projection https://en.wikipedia.org/wiki/Peirce_quincuncial_projection
