                          <!-- First, try the Python applet -->
      <object title="The Earth as seen from space" 
              classid="http://www.observer.mars/TheEarth.py">
                          <!-- Else, try the MPEG video -->
        <object data="TheEarth.mpeg" type="application/mpeg">
                          <!-- Else, try the GIF image -->
          <object data="TheEarth.gif" type="image/gif">
                          <!-- Else render the text -->
           The <strong>Earth</strong> as seen from space.
          </object>
        </object>
      </object>
