Two circles sharing a side of their inscribed squares (SoIS).
Another Pi "sandwich" enclosed by sqrt(2) and defining a "flutterby"
(includes SoIS, circle-squaring right triangle, and circle's diameter)

/ 2.0
= 1.4142135623730950488016887242097.. sqrt(2)

The "flutterby" incorporates a 45-degree angle
divided into 27.597.. and 17.402.. wedgies.

(27.597.. is smallest angle of that right triangle
and is the Quadraturial cosine angle)
