Programs such as Media Commander for Windows, HiJaak 95, and Image'N'Bits let you create thumbnails of each element and assign an appropriate label to each thumbnail. These tools make it easier to track the different data types that go into a multimedia application. Additionally, they allow you to create storyboard frames by dragging and dropping the thumbnail into a frame. Such tools typically use OLE and let you create OLE links from the presentation program to the data associated with the thumbnails. In that way, you might link a button on the screen with the playing of a video stream.
More sophisticated tools blur the line between storyboarding and development.
Storyboarding with such programs often results directly in an application. These products are also authoring tools and typically rely on an icon-based design language or a scripting language. BoxOffice enables you to create a storyboard, then use menus to make English-syntax scripts to link frames. When you're done storyboarding, you have a multimedia application. Allen Communication's Quest for Windows also has strong tools for developing individual frames and associating frames.
