Black Curvy Copter Puzzle
This is a brand new black Curvy Copter cube, designed by Tom van der Zanden. The Curvy Copter is a shape modification of the Helicopter Cube. Instead of normal planar cuts, the cutting line is placed at an angle of 32 degrees to give parabolic cuts. In addition to the 24 faces and 8 corners that need to be solved, the curved cuts reveal 12 edge pieces normally hidden inside the puzzle. The curved cuts also give rise to the beautiful clover leaf pattern on the faces.
