Reconstruction of the 1998 Danebury Hill formation
1.		Start drawing two concentric circles, a larger and a smaller one. The radius of the smaller one is half that of the larger.
2.		Construct a heptagon (7-sided regular polygon) inscribed within the larger circle.
3.		Draw the rays from the center of the heptagon to its corners.
4.		Extend the rays across the center, until they touch the larger circle. The set of lines touch the larger circle at 14 points, regularly spaced, forming the corners of a regular 14-sided polygon.
5.		Draw alternating seven of the sides of this 14-sided regular polygon, as shown.
6.		Construct 7 circles, each going through adjacent corners of the heptagon and touching at the smaller inner circle (at the side closest to it).
7.		Construct a small circle touching at two adjacent rays of the 14-sided polygon and also touching at the corresponding side of the heptagon (at the inner side), as shown.
8.		Copy this circle and shift it such, that its center coincides with a corner of the heptagon.
9.		Construct 7 circles concentric to the circles introduced in step 6, with a radius such that the new circle touches the small circle of the previous step (at the outer side), as shown.
10.		Copy and shift the small circles introduced in step 8 seven times such, that the centers coincide with the intersection of the last drawn circles (step 9) and the sides of the 14-sided polygon drawn in step 5, as shown.
11.		Now, all the necessary ingredients are ready.
12.		Removing all redundant lines…
13.		…yields the reconstruction of the 1998 Danebury Hill formation.
