Breaking news!
The KickStarter project has been sucessful!
Thank you all!
This die will be mass produced in March 2013!

Truncated Sphere D14 based on a cuboctahedron.
Numbered from 1 to 14.

A D14 numbered from 1 to 7 twice is also available.

This a new version with a better engraving and a new orientation that should give better results.

Truncated Sphere D15.

This die is inspired by the repulsive force polyhedra although in this case, the underlying polyhedron (not rounded) is very different from the shape that can be obtained through this technique with 15 points repulsing each others.
Actually, I calculated the positions of points (5 at each tropic, 5 at equator, none at the pole) 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 15 circular faces of same radius.

It is numbered from 1 to 15: all numbers are on edges.
The sum of the numbers on each tropic is 40 and the same applies to the equator.
Except for 8, all the numbers go by pair summing to 16: on the tropic two numbers symmetric relatively to the plane of the equator sum to16 and on the equator circle itself two numbers symmetric relatively to number 8 sum to 16. 

This die is made of a shell of 1.5 mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth.

Truncated Sphere D33

This is the Regular Edition of the 33-sided die specially designed to be the 33333rd entry of Kevin Cook's dice collection.

It is a big die (diameter is more than 30 mm). The thickness 1.5 mm and the depth of the numbers 0.75 mm.
There is still support material inside so it is also quite heavy...

The numbering has been carefully studied.
All numbers are by groups of 3 that sum to 51:
 - the 3 numbers at the North and South pole
 - the 9 numbers at the equator and at the 2 tropic taken 3 by 3 (any 3 numbers at 120°)
All numbers sum to 34 by group of 2 (except obviously 17, since only 17 itself can sum to 17 to give 34):
 - all the numbers of the poles and of the tropics with their symmetric number relatively to the equator
 - all the numbers of the equator (except 17) with their symmetic number relatively at number 17

The Happy Event Bead is similar the the Hollow Marble.
The difference is that it has slightly bigger holes (3 mm instead of 2.5) and these holes are not centered, so that the bead always shows the same side: this marble is intended to be used as a bead on a necklace without any holder (just insert the necklace into one hole and make it exit from the other one).
In this way, you can make a necklace with one bead for each significant event of your life (your own birth, your graduation, your wedding, etc. but it is mainly intended for the birth of your children).

Suggestion for the Mother Day: offer to your wife a bead with the picture of your children on one side and a text saying "Happy Mother Day 2011" on the other side!

Necklace not included.
