aerubin-Project-06-Curves

For this project, I was inspired by the polar curves we learned in calculus. I remember drawing them on the graphing calculator and adding them together to make cool designs. This polar curve reminds me of part of a flower, so I rotated it around itself to create one. The flower grows when the mouse is moved from left to right, and the number of petals change when the mouse is moved from top to bottom. In addition, I also added a bee that bounces around to establish the flower design. The bee can also be hidden behind the flower if the mouse is far enough to the right.
