This is a nice leisurely strathspey. It is not a published dance, as far as I know. It is a collection of moves to test out the various moves the applet can do. Shortly, this will contain actual dances, chosen at random each time the page starts up.
This is an Applet written in Java. If you do not see a Pillings-ish dance happening on your screen, then your web browser does not support Java applets. This is a terrible thing. I strongly recommend rectifying this immediately. You should acquire an updated version of either Microsoft's Internet Explorer or Netscape's Navigator.
