Green Flag. The Sierpinski Triangle is a triangle divided repeatedly into smaller triangles. There are many ways to create a Sierpinski Triangle. This project does not use recursion. Each time the triangle drawing sprite draws a triangle, it also creates 3 clones of the sprite. The next time we broadcast "Draw Triangle and Create Clones" broadcast there are 3 clones that draw triangles and each creates 3 new clones. We can only repeat this 5 times as 3x3x3x3x3 = 243. If you try repeat 6 times inside the project, we would need 729 clones which exceeds the Scratch limit of 300 clones. The Sierpinski Triangle then drawn is incomplete but strangely beautiful. Also you can "set size to 20" for the Sierpinski sprite and "show" the sprite. Then you will see lots of little Scratch Cat clones.
* See my Sierpinski Triangle studio * https://scratch.mit.edu/studios/3560462/ I saw a project to draw Fractal Trees using clones in the book "Computer Coding Projects For Kids" Using Scratch and applied the method to the Sierpinski Triangle.
