@SuppressWarnings("serial") public class Trefoil extends JComponent {
        setPreferredSize(new Dimension(400, 400));
    @Override protected void paintComponent(Graphics g) {
        Graphics2D g2 = (Graphics2D) g.create();
        int w = getWidth(), h = getHeight();
        g2.setColor(getBackground());
        g2.fillRect(0, 0, w, h);
        g2.setColor(getForeground());
        g2.translate(w/2, h/2);
        g2.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,

        int rays = 100;
        for(int i=0; i<rays; ++i) {
            double angle = i*(2 * PI)/rays;
            double flange = cos(1.5* angle - PI/4);
            int r = (int)(190 * flange * flange);
            int x = (int)(r* cos(angle));
            int y = (int)(r* sin(angle));
            g2.drawLine(0, 0, x, y);
        g2.dispose();
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable(){

                JFrame f = new JFrame("Trefoil");
