Working with the VSX team at Microsoft, Pablo Galiano of Clarius Consulting released an application called Storyboard Designer, a DSL tools based application that uses the VS 2008 Shell. Storyboard Designer does not require any version of Visual Studio to install, it only requires the free VS 2008 Shell (isolated mode) runtime installation. The application does not even target a developer. Storyboard Designer is for anyone who wants to diagram (model) and generate documentation for a storyboard scenario. There are screenshots on the CodePlex project home page, and Pablo also created a screencast video demo, see StoryboardDesignerDemo.
