Application variables can make it relatively easy to get the little featured movie widget up and running. Again, the idea is for a callout-style box, which cycles through each of Orange Whip Studio’s films, to display on the site’s home page. The box should change each time the page is accessed, rotating evenly through all the movies.
Listing 19.7 shows one simple way to get this done, using application variables. Note that the template is broken into two separate parts. The first half is the interesting part, in which an application variable called MovieList is used to rotate the featured movie correctly. The second half simply outputs the name and description to the page.
