The SPIN SeeLogo command can be used to create design that have a central symmetry, where the seed picture is rotated evenly around a point (determined by the position of the Turtle) a given number of times. In the following two examples the seed picture (a square) is the same but the result is different since the point around which the square was rotated changed. Since the SPIN command draws the basic SEED design and evenly turns the turtle, it is possible to achieve to draw the same picture using the REPEAT command alone.
SPIN 3 [BOX 40 40]
SPIN 3 [BOX 40 40 GOFD 40]
Part I: Load practice exercises and turn the red to black by using the SPIN command
