The flora of Funa. Beautiful in a fear inspiring way. Now all that
remains is to reduce it to mathematics.

Speaking of which:
If you move the grid over the centre and suppose a tangent on the arm
to the north, it is something like 45 degrees -within the constraints
of parallax imposed by the varying heights of the phenomenon, the
satellite's angle and the shape of my CRT monitor.

And on the arm to the west it makes an angle more like 67 1/2.

Leaving aside any aberration from a perfect spiral, anyone care to
guess at the degree of coincidence that the angles involved are so
closely related to each other?
