Move the linkage or drag the tiling.
Here you see "isolines" of the anlge of a specific vector (the direction of an edge in the linkage).
With the colored round buttons you can select which of the five colors is resembled.
The angles are directly transferred to the angles of the initial juzu.
From there the linkage is derived via the process described in the article.
One transition from wihte to full gray relresents a rotation by 72°.
The exact position of the isolines is calculated by a conformal flow that respects the symmetries of the desired coordinatization.
You can observe how one vector makes full cycles if you proceed constantly in transversal directions to the iso lines.
