Reconstruction of the
2000 Bringhurst formation

1. Draw a circle.

2. Draw six centerlines, evenly spaced at 30°.

3. Draw the diagonals (chords) closest to the centerlines.

4. Copy the circle of step 1 two times with their centers at the intersections as shown.

5. Copy the same circle one more time with its center at the intersection of the previous circles; it therefore passes through the intersections mentioned in the previous step.

6. Draw another circle, concentric to the previous one, passing through the intersection of two diagonals as shown.

7. Construct the circle of step 5 another 11 times (12 in total) regularly around the central circle.

8. Repeat this for the circle of step 6.

9. Turning back to the figure of step 3, construct a circle touching (tangent) to the diagonals.

10. Draw all centerlines equally spaced between the other set of centerlines (of step 2).

11. Copy the circle of step 9 with its center to the intersection of a newly drawn centerline and the circle of step 1.

12. Repeat this another 11 times (12 in total) for all other newly drawn centerlines.

13. Construct a circle passing through end-points of centerlines spaced at 120° and touching the small circle of step 9 (at the far side).

14. Construct a circle concentric with the one of step 1, touching the previous circle at the outer side. This circle forms the outer border of the formation's pattern.

15. Collecting everything introduced in steps 5, 6, 7, 8, 11, 12 and 14 provides all necessary ingredients.

16. Removing all superfluous parts finishes the reconstruction of the 2000 Bringhurst formation.

The final result, matched with the aerial image. It fits fairly well, but not accurately at some places.
