<p>The three dimensional puzzle is a cube made up of 56 small cubes and each slice and face of the cube can turn on a central sphere. Six identical spherical caps are held on this, along its perpendicular axes, by axles that allow them to turn. On each cap there are 4 studs, regularly spaced, that hold the small cubes and allow them to move. The studs have washers with grooves round them fitted on to them. The washers hold and guide the central and edge cubes by fitting into grooves.</p> |
