How to insert emoticons into google wave

This is .Net implementation of recently published python Google Wave robot supasmiley. This is a very simple robot that parses the text in a blip. If there is some text that matches standard character combination for emoticon display, it replaces that text with a google wave gadget to display graphical display. In this example, the robot is only looking for character combination <3. If it is found, the range of characters are removed and gadget is inserted. The gadget is a simple flash movie that display beating heart.

 void ProcessEmotions(IEvent e)
 {
  var txtView = e.Blip.Document;
  var txt = txtView.Text;
  var idx = txt.IndexOf("<3");
  if (idx == -1)
  {
    return;
  }
  txtView.Delete(new Range(idx, idx+2));
  txtView.InsertElement(idx, new Gadget("http://wave.byteblocks.com/emotions-gadget.xml"));
}
