        //draws each astroid curve with a number of points determined by the mouseY
        for (i = 0; i < mouseY; i++) {
            x = (a - (width/2)*j) * cos(i) * cos(i) * cos(i);
            y = (a - (width/2)*j) * sin(i) * sin(i) * sin(i);
            //places the point to be drawn to
            vertex(x,y);
        }
        endShape();
    }

}

I drew the astroid curve multiple times so that they could seemingly fold in and out of each other. This is manipulated by where the mouse is on the horizontal axis. I initially had the mouse’s y-height affecting the center of the curves, but it gave the user too much to vary in the curves. Now the mouse’s y-height affects the fidelity of each curve. Furthermore, clicking changes the color scheme between 2 options, just for some extra fun.
