This was a super fun project to make in terms of experimenting with curves and loops. I started out by setting up an initial for loop and just drawing one curve. From there, I established some more loops to duplicate lines, or played around with some of the numbers so that I could create different shapes. This is another project that I could definitely see myself playing with or changing in the future because it was so fun to make. Below I included some of my favorite screenshots of the composition as it moves around.
