Sophie is actually a tool to create and publish multimedia books.
from the site
Sophie's raison d'être is to enable people to create robust, elegant rich-media, networked documents without recourse to programming. We have word processors, video, audio and photo editors but no viable options for assembling the parts into a complex whole except tools like Flash which are expensive, hard to use, and often create documents with closed proprietary file formats. Sophie promises to open up the world of multimedia authoring to a wide range of creative people.
