Construct the part of the cylinder x^{2} + y^{2} = 1 lying between the planes z= 1 and z = x. 
Combine the above surface with its reflection across the place x = z to form this model. 
Join four cylinders of the same size symmetrically as thus: 
Join eight cylinders of the same size symmetrically as thus: 
Join six cylinders of the same size symmetrically as thus: 
Construct three mutually orthogonal "golden rectangles" whose 12 vertices form a regular icosahedron. 
Join 12 cylinders of the same size symmetrically as thus: 
Let
τ
denote the golden ratio τ = . Illustrate this interesting fact: the points [+τ, +τ^{1}, 0], [0, +τ, +τ^{1}], [+τ^{1}, 0, +τ], [+1, +1, +1] comprise the vertices of a regular dodecahedron.
