The nose function got me stuck for a while, mostly because I tried to relearn how to measure
chord length of a circle so I could trig my way into an exact position of the turtle to make
the swoops for the septum/upper lip of the dog at the base of the nose, but after much math, I found
myself estimating anyway, so the only real known that I *needed* was the x-dir midpoint, which I knew
and from there I chose some reasonable numbers that make the bottom of the nose look as intended.
I'm finding myself not stuck, but challenged, with the final layout of all of the parts of the face. I think
I'm going to be in the same boat as before where exact values aren't really needed and I have enough info to
estimate a "close enough" position for how all of the parts come together. Order of operations is also
going to be important here because some of the shapes need to go on top of others to get a layering effect.
So far the biggest sticking point has been the planning, mostly from the standpoint of
designing a drawing that I will realistically be able to create with turtle. I want to make
a dog, so I was going to make a pointer (my dog) holding point, but the curves were
complex and I couldn't quite figure out how I wanted to integrate iteration into that design.
I've since decided on a dog's face, where I can use a lot of the same shapes in a variety of
locations, so I'm hoping that continues to work. The ear() and face() functions that I have
right now generate two different forms of ellipses, one sort of football-shaped, the other much
longer and narrower, proportionally.
