An origami rendering of a six-piece burr puzzle. My original intention was not to make a puzzle; I just wanted to model the overall shape, a stellated rhombic dodecahedron. I was beguiled by this polyhedron (I'd encountered it in a couple of Escher prints when I was a much younger monster), and experimented with various modules of my own design in order to make it. Then I found instructions for the origami puzzle which incidentally shared its shape. I may go back and try again; I think the components from the intersecting octahedra model could be modified to construct the shape I want. (I also learned via Wikipedia that this polyhedron can tessellate three-dimensional space; by implication, the pieces of the burr can do the same.)
