Golden Circle

This circle is completely filled with golden rectangles. A golden rectangle is a rectangle with a ratio of side lengths equal to φ=1.61803398874989484820458683436564, historically known as the "golden ratio".

I started constructing this manually in TurboCAD when I realized I could write a program in Visual Basic to render the image I want, in high quality and full color.

The title and VTK logo were added in Paint Shop Pro as the last step.
