One of my favorite puzzles over the years. The eight different challenges consist of 8 cubes to be assembled inside the walnut cage. This puzzle won the Grand Prize in the 2003 IPP Design Competition ( http://www.puzzleworld.org/DesignCompetition/2003/results.htm ). I'm selling the puzzle to make room for future acquisitions.
