Tree of Pythagoras

From Fmepedia

The Tree of Pythagoras is a workspace created by Michael Habarta.

Michael says... By recursively adding 2 quads to a base quad according to the graphic illustration of the law of pythagoras (a2+b2=c2) a tree is created.

By choosing a start size, ratio (a:b) and limit you may vary the resulting tree ... Here's the workspace.

Some screenshots ... (some more are attached):

...this one with start size 100, ratio 0.5 and limit 3

...this one with start size 100, ratio 0.75 and limit 4
