Copy of Fractal Tree
I was trying to learn how to use the sequence command to make a fractal tree, but instead I just made a fractal tree.
The sketch uses the pattern of the first 4 points to make branches on later points scaled to the length of the branch.
Try varying the points A, B, C and D to see what kind of patterns you can make.
