For this project, I started off with browsing mathworld website and finding the curve that we would want to use. I chose hypotrochoid. Then, I tried to generate that curve through coding, and what I found out was at some point, the lines that I made through the equation I chose made an eye-shaped form at some point, so I restricted the mouse movement to have it start from the shape and added wiggly circles in the middle of those lines. I added the wiggly bubbles in the back because it felt like it needed some more elements to it to have some sort of a visual balance. I kept all the colors white, because I did not want it to be way to literal in communicating my “zooming into an eye” idea. Below is the screenshot of the shape I got inspired from.
