Okay, I've got my trusty pet turtle here and he's going to demonstrate what I mean by a line contour drawing done on the computer. So the deal is a vector, you know, a vector image. There are coordinates and lengths and all of these things specified in order to draw the shapes. I just want you to think about drawing a shape using a completely different representation. And in this one, there are further constraints on what you can draw. So you should be able to get a pretty compact representation. All that you can do is tell the turtle, this pen is always down on the paper. All you can do is tell him which direction to face and we're going to do that left and right by degrees. And then to move forward and you can tell him how far you move. So, you know, some distance. Anyways, so just to demonstrate that, I'm going to have my pet turtle chibi here is going to draw something. So the first thing we're going to do is have him move forward 15, 15 units, whatever that is. Notice his pen is down so he's made a line. And then we're going to orient him to the right 90 degrees and have him move forward again. So, this time I'm going to turn left. I'm turning quite a bit left. I think we're 35 degrees. And let's see. Let's move him 14. Thank you.
