In this workshop we will study the structure of some of the complex and beautiful sculptures by George Hart. Knowledge of the geometric concept of stellation is fundamental to understanding how these sculptures are designed and constructed. We will learn how stellation is used to produce complex polyhedra. The author has designed a simple puzzle sculpture kit based on this concept. Each participant will assemble one of these kits. Constructing and studying this small sculpture will enhance the understanding and appreciation of George Hart's creations.
