Recursive Pythagorean Tree

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration recursively generates Pythagoras trees made of selected images. Each square within the tree can be a solid color, an image from Wolfram Language ExampleData or a Spikey. In addition, you can choose the angles of the triangles, the number of levels within the tree and the resolution of each image.
