    for (int i = 0; i < borderDim; i++)
        g.drawRect(i, i, size.width - 1 - i * 2, size.height - 1 - i * 2);

    FontMetrics fm = g.getFontMetrics();
    int sWidth = fm.stringWidth("Initializing...");
    int sHeight = fm.getHeight();
    if (sWidth < size.width && 2 * sHeight < size.height) {
        g.setColor(Color.blue);
        g.drawString("Initializing...", (size.width - sWidth) / 2, size.height - 2 * sHeight);
