Group for User Interface Design has developed a quite extraordinary piece of software for prototyping called DENIM, which is free for download at their web site. With the tool you sketch sitemaps, storyboards and page layout by hand and work seamlessly between the different levels of detail by zooming in on items.

Unfortunately the tool is developed for pen interaction and is very hard to use with a mouse. But if you have a pen tablet or a touch screen you might find it handy.

But check out the video presentation anyhow
