I'm not sure how useful a traditional pen-and-paper sketchbook is to a web designer, but for those coders who like to visualize their work offline, this Web Design Sketchbook is perfect.

The pages of the Web Design Sketchbook are laid out like a Firefox browser, complete with toolbars. Now your blog or site can be sketched out in realistic detail, limited only by your own ability to draw a straight line.

Implications - This combination of computer technology and traditional notebook-style writing is a refreshing hybrid and certainly has me thinking about the Firefox notebook! After all, who wouldn't enjoy a sketchbook as badass as this one, and I'm sure it will be a huge help to blogs everywhere.
