New view of the world:

'Tokyo-based architect & artist Hajime Narukawa won Japan's prestigious Good Design Award for developing the AuthaGraph World Map, a groundbreaking projection that preserves the true proportions of continents & oceans.

By dividing the globe into 96 triangles, then transferring these to a tetrahedron & unfolding it into a rectangle, the AuthaGraph map eliminates the distortions found in both the Mercator & Dymaxion maps'

Clarification: this is not a newly-developed projection. It was created in 1999, and it won the Good Design Award in 2016 according to [Wikipedia](https://en.wikipedia.org/wiki/AuthaGraph_projection).

And it's a special case of a polyhedral map projection [1]. My guess is that it's the Lee conformal world in a tetrahedron projection [2]. Cut the corners of the triangle and rotate and paste back together the cut pieces and the triangle becomes a rectangle where the mapping is continuous internal to the rectangle.
