This one took a whole lot of time, almost solely because of the intersections of the red and blue beams. In addition the details became a bit small because I run with fixed line widths over all my figures. I do not plan to change this, but I do wonder sometimes.

In addition to the two beams that repeatedly pass over and under each other being perfectly horizontal, they also connect vertically at each end, and if you travel around the figure you will notice that you will either go only up or only down at the ends.
