Here a slide show is driven by an audio file attached and played with the Sound object, or actually, an "Audio" object which is a wrapper for the Sound object (this object is defined in a movieclip in the libaray and is accessible to the main movie thanks to #initclip). Based on the position of the audio playing, the movieclip containing the slides will appropriately navigate to the correct frame based on an array of times defined in the main timeline. Navigation controls are given to play, pause, and skip forward and back through the slides.

The audio and slide show discusses a brief description of camel spiders.
