This sculpture is a pretty 3D polygon (see “Pretty 3D Polygons: Exploration and Proofs”, Melissa van Veenendaal and Tom Verhoeff, Proceedings of Bridges 2021, pages 111–118, https://archive.bridgesmathart.org/2021/bridges2021-111.html), with roll angle 𝜓=90º, roll angle signs (+++---)³, and turn angles alternating between 𝜑=90º and 𝜑≈151.6º (more precisely: 𝜑 satisfying 3√2 cos(𝜑/2) - √2 cos(3𝜑/2) = 2) . Thus, the 18 beam segments are all congruent. The beam segments have a square cross section and are connected by miter joints. It won the second place in the Wolfram Computational Art Contest 2022. Hans de Koning constructed the wooden version of the sculpture submitted for this exhibition.
