C. shape variations of the 3x3x3 cube because the cubies always maintain the same in-out orientation relative to the center of the cube, cubies can have any surface extension desired. Therefore there are cubes are spherical cubes, cubes with corner pieces trimmed to equilateral triangles, some edge pieces are trimmed so that they make a single plane presentation (eg, makes a barrel), I HAVE NOT HEARD OF ANY THAT MAKE A SOLID SCULPTURE OF THE CUBE, eg, a bust of RUBIK.
