I saw this book in this CNN Video on The Sketchbook Project site. I took some screenshots because I thought it looked so cool!
It's like a tunnel book, but with accordian-like pages that allow each section to close up to show some word/phrase. Check it out:
Looks simple enough! Maybe for my next project...
The Sketchbook Project seems pretty cool, too. You order a small Moleskine Cahier sketchbook, fill it with whatever (based on the theme they give you), then send it back to be included in their collection of thousands of sketchbooks. They have traveling exhibitions, too, and you can list your sketchbook for sale (for any price you want), so someone could buy it!
I bookmarked the site... I'll think about participating. Sounds like a cool opportunity.
