The structure in this work, part of an ongoing investigation into the use of five-fold symmetry, is based on the form of a copper dodecahedron. Within this form sits a tetrahedron made of high-reflectivity glass. These two Platonic solids connect at the four corners of the tetrahedron. At the center of the sculpture, a halogen bulb is suspended. In an interplay of reflection and shadow, interior and exterior, the glass reflects the five-fold pattern when the light is off, while the pattern is projected onto the walls of the surrounding space when the light is on.
