I have created new google code project for hosting all the code sample which I use through out the series of design pattern.
you can get it from here
you need svn client, for downloading this code sample.
Update on screencast: As I promised earlier, John and I are going to record screencast on each of the pattern, as we post them but so far other personal/work stuff has kept us busy so couldn't record any. Stay tuned at http://feeds.feedburner.com/mahendramavani for these screencast.
Very soon, I will be posting next one in the series
