Product Description
Truncated Sphere D9.

This is my own interpretation of the D9. Please check also clsn's version. Compared to the picture, number nine is now underlined instead of being followed by a dot: the new standard is now to have the highest value underlined to easily distinguish the different types of dice that have become very numerous.

This die is inspired by the repulsion force polyhedra. In fact, the underlying polyhedron (not rounded) looks like the shape that can be obtained through this technique with 9 points repulsing each others.
But in this case, I calculated the positions of those points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere. The result is a truncated sphere with 9 circular faces of same radius.
It is numbered from 1 to 9: 6 numbers are on vertices, 3 on edges, none on the faces. The sum of the numbers on the upper vertices is 15. Same thing for the sum of the 3 numbers on the lower vertices and the sum of the 3 numbers on the edges. This numbering is closely linked to the well known 3x3 magic square.
