There have been numerous maps on the LANDmasses of the world, but what about the oceans?
There are five+ "continents":
Arctic
Indian
Pacific
Atlantic
Southern
Pacific could be divided into 2 because its so large.
Atlantic could also be divided north/south.
This map would best be represented on a globe rather than a Mercator map, so I would suggest something like the wikipedia's image.

Another possibility is to invert all the terrain and make a mountain range out of the marina trench in the pacific, for example.
I'm not a map maker, but I thought the idea was cool, so if anyone wants to do something with this, It's fine by me.
