For this project, I had a really hard time to figure out what I really want to do because I personally don’t like string art which seems to be too scientific for me. However, after seeing the provided examples, I start to understand its beauty. I first analysed the Holly Hatfield’s blog on “7th Grade String Art” to figure out the algorithm. Once I understood how curves were created, my project became easier. My intention was to create a unique style of an eye where the spinning eyeball will appear once your mouse is on the pupil. After I finished creating the project, I felt my algorithm was too simple so I started figuring out how to make gradient curves (which is shown and explained in the comments). The whole process was fun and improved my understanding of this language.
