The first time you open the book, you can choose any of the four main characters to play or read, after you watch a plane landing in Las Vegas. The plane landing, and this opening screen, were executed in Flash. However, subsequent pages are executed solely in DHTML. When Vegas, Baby! receives a request to view this page, it makes a note in a file in your Temp Directory so that the next time you open the book you won't have to sit through the animation again.    Back to Vegas, Baby!
