1. Triangle Fractal in Snap! with Recursion.

   

2. Create a new block "triangleFractal" with two input variables. Choose "Motion" category (blue) and type "triangleFractal" for the name of our new block.

   

3. The triangle fractal can start drawing at x=-150, y=0.

   

4. At level=1, all that is done is to move the length of side. Here a line of 300 is drawn.

   

5. At level=2, you begin to see the fractal shape. Each move is 1/3 of 300 = 100.

   

6. At level=3, each of the line segments from level=2 has a fractal on it

   

7. The higher we start level, the smaller the fractals will get.

   

8. Starting at level=5 has tiny fractals.

   

9. Here is the block code for this fractal. There are 4 recursive calls to itself.

   

10. Here's a fractal snowflake - the Koch snowflake - made with 3 fractals together.

    

11. Try to make this square fractal.

    

12. Again, starting the fractal with a higher level gives a more detailed fractal.
