Test Pattern Radio was an online internet radio station in existance from October 2001 to February 2003 and composed of around 30 international hobbiest broadcasters. While the project no longer exists, you can still see snapshots of what it was like.
From time to time, scripts were made available to the public. These scripts are still available, if somewhat dated.
