Pepakura: Unfold Anything
Now this is cool. Lee, since you have previous 3D experience, would you try out the unfolding program "Pepakura"? The demo is free. Open a polygon model and it will create a pattern for a cardboard fold-up. It looks like it could be sooooo cool. Great for quick, visuals in real 3D. You just cut them out of cardstock or matboard.
