Rotating Squares

Create a new Scratch project, and construct the following program. Or, you can download the starter program here.

Now consider a program that produces an output like this:

If you look carefully at this figure, the simple square shape that the original program would draw just once is now being drawn six times (each one rotated a bit more than the previous one), so we get a circular overall shape. Making this modification will consist of adding a repeat loop which will enclose the existing repeat loop (in other words, you’ll end up with a repeat loop inside of another one). In addition, you will need to add a “turn” command.

For this problem, modify the starter program to output a drawing like below, drawing precisely 36 squares.
