Denim: Rapid prototyping tool

[from a Usability list] Was pointed in the direction of the Denim and Silk applications developed at the Group for User Interface Research at UC Berkeley for rapid prototyping of Web user interfaces. The application supports the way IA's work in 2 key areas: site mapping and page level wireframing. It allows you to sketch the content topology, sketch wireframes for pages, and connect them within the tool. It then builds the click-through of the sketches in HTML. There is a nice realvideo video demonstrating the tool on the bottom of the page. Check it out. It looks like an excellent start.
