Pythagoras Tree

The Pythagoras Tree is a fractal created with the following process: Begin with a square, and then create two duplicates scaled down by sqrt(2) / 2. Position the duplicate squares on top of the original such that the space between the three squares is a right triangle. This process is repeated by applying this process to the original shape and adding the scaled version to the branches.

The OpenSCAD code used to create this model is included, but it should be noted that the STL exported from O
