The Chestahedron is the first heptahedron of this configuration in the history of geometry. This sculpture has 7 surfaces (consisting of 4 triangles and 3 quadrilaterals), 7 points and 12 edges. By applying an alchemical transformative process to his seven-sided form, Frank has discovered many previously unknown geometric structures that demonstrate a remarkable correlation to the form and functioning of the human heart.
