Building a Binary Tree fractal

1. We begin by drawing a vertical line segment (the trunk).
2. Click the + sign in Iterations to add 2 branches with a 30° degree inclination.
3. Each time you click the + sign, more branches are added at the end of each branch.

You can also change the angle used and add a random factor.

Building a Sierpinski Triangle fractal

1. We begin by drawing a triangle.
2. Click the + sign in Iterations to add an inverted gray triangle inside.
3. Three new smaller white triangles are created, click the + sign again to add inverted gray triangles inside each new white triangle.

Building a Pythagorean Tree fractal

1. We begin by drawing a square.
2. Click the + sign in Iterations to add two new squares scaled down by a factor of √2/2.
3. Each time you add an iteration, new smaller squares are added.
