Not to long ago one of my developers came across a little mockup tool called Balsamiq and then I saw a post from Clark Ching who checked it out as well. I love the sketchy look and feel and rendering a quick mockup form was good fun. We’ll probably try it out on a future project and see if we can get some value out of it. Much like the Swing Napkin look and feel the value is from being obvious that this is not to focus on look and feel, but more on the functionality of a web site.
