I've posted a demo of a few display capabilities of the Dataform - http://substantialmethods.com/subject/view.php?id=4&topic=8. The entries are simple and consist of one image. It would work the same for complex entries with different field types. The random or otherwise entries are displayed in a section by means of the Dataform embedded resources. There is also a block that displays a random image from that gallery. The gallery is hidden on the frontpage.
