Easy readable binary encoded highly symmetric die.
(designd for glass printing, not tested yet)
This die was designed so that the value representing markings
preserves all the symmetries of the cube-faces
namely one fourfold rotation axis
and four mirror planes per face.
The markings are encoded in binary.
But you don't need to know that to read it!!
Due to the quadruplication and overlapping
of the marks the die is easy and naturally to read for everyone.
Just count all pluses of the whole face and the minuses of only one edge and add them.
If you want to read it in binary and fully understand the system
here is how it works:
You read three bars from the center of one edge.
The bar in the center of one edge counts one (it overlaps exactly with its mirror image).
The bar between the edges center and edges corner counts two.
The bar near the corner counts four (it forms a plus by overlapping with its mirror image).
