I was really drawn to the ellipse envelope curve that I came across on the Math World website. It reminded me a lot of the second exam question about the bezier curve made of descending lines. With my interaction, I really wanted to showcase how the curve is made out of a defined number ellipses, so I made it so that my start state showed regular ellipses transforming into the ellipse envelope through the changes in their x positions, y positions, widths, and heights. I used the constrain function in order to make sure that the ellipse envelope isn’t broken after one’s mouse passes the screen.
