A wooden surface
A wooden sculpture of Franco Badaracco's. From the point of view of topology, it represents a torus, that means a surface of genus 1, that can be seen as a doughnut with one hole, or as a sphere with one handle attached.
You can see other frames of the same subject, from which the shape is more difficult to recognize.
