Project 11- Composition-sehenry

I tried a bunch of different ideas for this project but in the end I wanted to keep it simple. I created two turtles that would draw and rotate themselves in two different positions and in the end I thought that it kind of looked like a tire on a car. As a result I drew a road and a sign that says how far carnegie mellon is from my home while the tiring is stitching itself together before it hits the road. I think it worked out well.
