PageDisplayLooperProduct is a little container for having a slideshow of websites.
You create either URL objects or Website objects. URL objects simply hold a url property and a timeout value. The websites are little websites on their own. Like Zope folders. They too have a timeout value.
The container has a nifty little management interface which is easy to use. The looping only works in Internet Explorer because it is using a Javascript to update a nearby frame. The product was originally developed to be used on TV monitors in a schoolbuilding corridor. There they used to have PowerPoint slides but figured that webpages are easier to administer.
Install the product and then import the example file.
