Several months ago I completed a Scratch project on the golden
rectangle of mathematical, architectural, and artistic fame. Below is a
screenshot at the completion of a run of the scripts.

The first script draws a series of squares, starting with the largest
square on the left. It continues drawing successively smaller squares in a clockwise
spiral. Each square cuts the larger golden rectangle into a a smaller square and a
smaller golden rectangle.

I have now written a pdf
file that describes a bit of the history of the golden rectangle, its
relationship to the Fibonacci numbers, and the cool script that draws the
spiral. When given the radius and arc length, the script draws the arc with
that radius. Scratch (unlike Logo) doesn’t have any circle tools so if Scratch
2.0 really lets us create our own “blocks” then I will make this script into a
block and write other circle tools.

The free pdf file
can be had by sending an email request for
