In mathematical terms, this is a Stellated Dodecahedron. It hardly qualifies as a turning; only the small redwood spheres are turned. There are 60 triangular windows, each displaying a different species of wood. The framework is walnut. The little white dots display a number that identifies each wood on a reference sheet. I won’t bore you with the listing. There are sixty-two different species of wood. The windows are numbered and referred to a reference sheet. It could be used to support a glass top.
