Statement
For several decades I have been exploring ways to turn mathematical models into small geometrical sculptures. Often, I start with a particularly intriguing sculpture by a recognized artist. For this exhibition I have been inspired by Tord Tengstrand’s “3-2-1”-sculpture. This small model gets its name from the fact that it has three edges, two vertices, but only a single, wildly branching-out, smoothly connected face, which borders itself along the three edges. I have created derivative designs with more than two vertices, inspired by Tengstrand’s sculpture.

For this model, I have used half of Tengstrand’s “3-2-1”-sculpture as a pliable corner module with three legs. I bent these legs outward, so that adjacent legs end up perpendicular to one another. I then placed eight copies of this module at the corners of a cube and joined the 24 legs to form the 12 edges of cube frame. I maintained the helically twisting sharp-edge-curves as they were in Tord’s original. This led to an intricate edge configuration that splits the surface of this handle-body into four smoothly connected faces with the topology of a warped 3-sided bi-pyramid. The four faces are shown in different colors.
