Reading the project description, I was very intimidated by this week’s project due to all the complicated formulas and many options. I think I was drawn to the butterfly curve because of the shape and the complexity of it. I wanted to make a pattern out of these curves while it would turn based off the mouse’s position. Based on the mouse position, the curves would change and the lines would make different positions.
