Object: Open the box.Slide the pieces around so that the hidden ball will come out of the puzzle, and then you will be able to open the box. There are moving layers underneath the decorative cover that slide around several pins. You can just see enough through the holes to begin to understand how the moving maze works. The outer workmanship on this box is really stunning, and it doubles as a really attractive showpiece.Made by Jean-Claude Constantin, who lives in Germany, where he designs and manufactures many different wood and metal puzzle, as well as magic tricks.
