Both turtles and patches can create visual images in the NetLogo view. Create a turtle and have it draw a circle (using the PEN-DOWN command). Create the outline of a circle with patches without using a turtle pen. Write a procedure that asks a turtle to draw a square given a starting location and side length. Write a similar procedure using patches.
Compare and contrast the code for these two procedures. Which set of code is more compact? Are there advantages or disadvantages to using patches or turtles to accomplish this task?
