The image below shows you the structure of a Media Station. It is just a very simple example. You can add more slides (image slides, text slides or branching points) to each slide sequenz, more slide sequences to the media station and you can add more choices to the branching point. Of course you can also remove slides, slide sequences or choices of a branching point.
The slide types (image slide, text slide, branching point) are also just an example. You can replace every image slide with an text slide or branching point, every branching point with an text slide or image slide, and so on. So in the end, you can have a very complex structure of slides.
