Reconstruction of the 2001 Hurn formation
1.		Draw a circle; this will form the outer circle of the formation. Draw the horizontal and vertical centerlines.
2.		Construct a regular heptagon (7-sided polygon), inscribed in this circle, with one angular point at the right end of the horizontal centerline.
3.		Draw the rays from the center of the circle to the angular points of the heptagon.
4.		Draw the rays positioned in between rays 3, intersecting the sides of the heptagon at their midpoints.
5.		Construct the inscribed circle of heptagon 2. It will form the inner circle of the outer ring of the formation.
6.		Construct another heptagon, parallel to heptagon 2, inscribed in circle 5.
7.		Construct again an inscribed circle, this time of heptagon 6.
8.		Draw a line from intersections of this circle with rays five apart, as shown.
9.		Construct a circle, concentric to the previous ones, tangent to line 8. It will form the outer circle of the inner rings of the formation.
10.		Draw a line from intersections of this circle with rays three apart, as shown.
11.		Again, construct a circle, concentric to the previous ones, tangent to line 10. It will form the middle circle of the inner rings.
12.		Draw a line from intersections of circles 7 and 9 with rays six apart, as shown.
13.		Construct a third circle concentric to the previous ones, tangent to line 12. It forms the inner circle of the inner rings.
14.		Construct a circle with its center at the intersection of a ray and circle 7, and tangent to the rays next to it, as shown. (By the way, this circle has exactly the same size as circle 9).
15.		Draw a line from the intersections of this circle with circle 5, as shown.
16.		Copy a circle 14 with its center at the intersection of this line and the same ray (as circle 14).
17.		Repeat this another six times for every other ray (up to a total of seven).
18.		Leaving out all unused parts yields the reconstruction of the 2001 Hurn formation. (Black denotes flattened crop).
