For this project, I was inspired by the spirograph curves. I created a set of ellipses that change based on mouseX and mouseY parameters. The mouseX changes the color of the stroke and the angle of rotation for the ellipses. The mouseY changes how many curves are drawn and the width of the curves. Additionally, when the mouse is clicked the strokeWeight will increase. When any key is pressed, the strokeWeight defaults back to its original value.
