I found this project to be really difficult since I did not know where to start. I ended up just trying to use the lerp() function until something showed up on the canvas, but once it did I began to understand what I was doing. Throughout the project I was able to learn how to grow and shrink lines and move them around. Overall, I found this project to be very informative and interesting to learn.
