OVERVIEW: This screen allows for an immense amount of material on a single topic to be collected together and sorted in layers. It is an ideal screen for an in-depth exploration of any topic, especially when a variety of media (video, images, and text) are available. The main screen includes a place on the upper right for introductory text which will be constant on all layers. It also has a large image which can be linked to other screens or URLs, and two thumbnail images which can be linked to other screens or URLs. Authors who do not want to have a screen link can instead have video clips attached to the larger image and/or any thumbnail. Authors also add a title for the layer, and there is a place for text specific to the layer. Example
