This is a simple example of using the library list zipper implementation to implement a basic slideshow functionality allowing remote commands to navigate to the next, previous, first, and last slide in a sequence of slides. The slides are represented using a predicate with two arguments, the index and the slide contents. The main predicate, show/2 takes a sequence of slides and the name of the predicate, which is used as a closure for displaying the slides.
