Drawing spirals
You can draw two types of spirals: symmetrical and logarithmic. Symmetrical spirals expand evenly so that the distance between each
revolution is equal. Logarithmic spirals expand with increasingly larger distances between revolutions. You can set the rate by which a
logarithmic spiral expands outward.
