AuthaGraph Globe is a paper craft assembly kit. Three globes with different shapes are in one volume, sphere, tetrahedron and one in between sphere and tetrahedron. By assembling this kit, you can three dimensionally understand the process of how the AuthaGraph World Map is made of.
The composition of the three globes shows the process of how to project information on spherical surface to rectangular surface.
A globe shaped an inflated tetrahedron fits in a spherical globe.
A tetrahedral globe fits in the globe shaped an inflated tetrahedron.
A rectangular world map is obtained by unfolding the tetrahedral globe.
