This Demonstration shows acute golden rhombohedra, icosahedra, rhombic icosahedra, golden octahedra and golden tetrahedra augmenting a helix. The basic unit is a ring of 10 acute golden rhombohedra with an attached rhombic icosahedron forming two helices featuring a closed tubular structure. The backbone of the structure is formed by one acute golden rhombohedron from each ring of 10. Rhombic icosahedra units are attached face to face and meet with golden tetrahedra at the subsequent turn of the helix. Each acute golden rhombohedron is divided into three parts, which form golden octahedra and golden tetrahedra rings.
