     <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>
