However, it's a RECTANGLE, that's huge. that means we can use it on screens and that non-map geeks would be OK with it.

What does it mean, "as accurately as possible"? Is that stretched-out Brazil accurate? Or that shrunk China? Pretty sure a lot of areas of this map aren't very accurate.
Do you think it may be your bias based on your entire lifetime of looking at Mercator projections? The purpose of this project is to make it an accurate representation. The observations you make are precisely why this made was made.
To get the rectangular final shape one of the 4 triangular-surfaces is split into two and rotated to the neighboring sides. (Much like that one triangle south of Australia on a Dymaxion map)

It tiles, so it can be used for web maps, you can just rotate it slightly and always have it north-pointing, so it can be used for mobile maps, and it shows the world in an equal view. And it doesn’t distort the shape of continents either, only the composition. This is amazing.
What do you mean the continents are not distorted. South America looks pretty distorted to me, so does Australia.
> "AuthaGraph... faithfully represents all oceans and continents" What does this mean? Literally, that is impossible, so what's it actually preserving and distorting? It looks like angle is distorted. Is that it?

For one thing there is massive distortion of relative distances in southern parts... New Zealand or Australia to Antarctica is something like 4 hours flight, not halfway across the planet.

But map should be accurate in the first place. It's not like you can just ignore things you don't want to see there just because they are naturally to big and take up too much space
Actually humans can do that. We orient ourselves using landmarks. If you look at theme park maps, ski resort maps, maps of tourist areas downtown produced by local organizations, subway maps.... All of them are wildly inaccurate in terms of proportions and distances. But notice - almost all are oriented to people not very familiar with that area. Certain big monuments may be left out (the highway that runs by water p…

Cutting the map in the Pacific just makes a lot more sense rather than cutting it in the Atlantic. Do we really need most of the space in the middle of the map to be water?
I'm not sure about the why. Maybe because it puts the target countries more towards the center of the map rather than the periphery?
