A minimalistic puzzle that uses two different axes but is still doctrinaire.
Bram's Sphere is a twisty puzzle that is based on a geometry invented by Bram Cohen. The puzzle has only two rotation axes, one with 3-fold symmetry, one one 4-fold. Despite the bandaged look and the stored cuts, the puzzle is actually doctrinaire. In order not to obfuscate the geometry and stay closest to Bram's orginal design, the puzzle is shaped as a sphere.
It is a close relative to the Solver's Chop or Modular Cube but unlike that it has different cutting depths and therefore these pieces:
1 square face
1 triangle face
5 X-pieces (different)
Oskar later presented "Bram's Shere inverted" with different cutting depths.
