(5,1)-torus path from 24 segments with a square cross section,
connected by regular miter joints.
The original sculpture is made from wood:
its beam is not painted but constructed from four separate beams (2 dark, 2 light) with a right-angled triangle as cross
section, glued together into a square beam.
The path exhibits a 180-degree Möbius twist,
so that the light surface forms one continuous strip,
and similarly the dark surface.
Thus, the front view is light and the back view dark.
