Like its smaller cousin with a single floating cube (3d Puz Pyramid - Cube), this puzzle is extremely elegant, novel, works well on a desk or table, and looks simple - but, I can assure you,  it is not! 

When you first see this puzzle, you see 3 cubes floating in a pyramid - a very nice optical illusion. 

The puzzle seems simple - simply remove the 9 seemingly identical rhomboids and then replace them..... way easier said then done.

Even when you know what you are looking at and realize that this is a cunning packing puzzle, it is still non-trivial to put the pieces back.Each of these puzzles is hand made; no two are exactly alike.Enjoy!
