D.I.Y. Harriss Spiral

[b]What is the Harriss Spiral?[/b] The Harriss Spiral, a fractal spiral, is composed of golden rectangles, divided into smaller golden rectangles [long side is 1.618 times the short side] and a square. The definition of a golden rectangle says its longer side must be 1.618 times the shorter side. In order to create the spiral like Harriss, it is necessary to connect the shapes with quarter archs. In this program, each rectangle one creates is interestingly subdivided to into the two similar rectangles and a square. The ratio 1.325, the plastic number, is shared between the sides in the two similar rectangles. [b]How is it different than the Golden Spiral?[/b] Instead of cutting a square, as done in the Golden Spiral, which leaves a golden rectangle, initially cut out a rectangle.
