These pieces are studies for using the Zipform system (created by Emily Baker and Edmund Harriss) for the mathemalchemy lighthouse, in collaboration with Sabetta Matsumoto, who made the models with Ásgerður Johannesdottir. The zipform system takes flat cut pieces and connects them at right angles creating a beam along any curve. It was initially used to create beams lying on a sphere where one of the surfaces of the beam will always match the surface. Other surfaces are more restrictive, and the beam must follow line of principal curvature where the ribbon of surface bends but does not twist around the tangent. These models show a possible construction for a hyperboloid and for a small pertebation of the hyperboloid to give a helical path.
