Hello, I've been working on a version of the turtle hiding inside his shell, its not ready to post yet, but I do have a "Pre-Loader" animation I completed a while back. I had purchased a book by Chris Georgenes and Justin Putney "Animation with scripting for Flash Professional CS5". I'm currently working through it and have found this book to very informative and well worth the read. (I used snag-it to video capture the swf).
