Does anyone here know of any good trainings, videos, articles, instructions on wireframing and creating high-fidelity mockups in Illustrator? I'm also open to a list of trainers that specialize in this. I'm not finding much on the web - a lot of the focus in rapid prototyping (including on the Adobe website) seems to be with Fireworks but i know there's a strong community that uses Illustrator too! Thanks everyone.
