This bizarre yet pretty shape is said to be foldable into a tetrahedron. The tetrahedron is a six pointed star, in other words the shape of the star of david in 3D. If you fold the thing to the left on the centers of the hexagons in the right way it should produce the right form. Also notice the sets of four circles within the photo. Maybe they are to help us fold this immense craft of mammoth artistic playfullness? Who knows, all I know is that it is an interesting design. More of a crop formation than a crop circle in this case.
