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 threefold symmetry, one one fourfold. 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.
