You can try something I wrote a few years ago:

http://www.adapower.com/index.php?Command=Class&ClassID=Patterns&CID=272

http://www.adapower.com/index.php?Command=Class&ClassID=Patterns&CID=273

There are other articles on that page:

I haven't updated these for Ada05, but I assume adapting it to use the
new interface types wouldn't be too difficult.
