Sqetch – An Illustrator Wireframing Toolkit
While I've made my opinions of sketchy wireframes very clear, I have to say that Sqetch provides a gorgeous bridge between hand-drawn wireframes and their computer-created counterparts.
The components have a high visual fidelity, while conveying the incompleteness that many designers seek when they use "sketchy" wireframing tools and templates.
The toolkit provides all of the expected GUI elements that most designers would need, including those for the iPad and smart phones.
Interactive Sketching Notation
"The interactive sketching notation is an emerging visual language which affords the representation of interface states and event-based user actions. Through a few simple and standardized rules, what the user sees (drawn in greys and blacks) and does (drawn in red) are unified into a coherent sketching system. This unification of both interface and use, intends to enable designers to tell more powerful stories of interaction."
