I have received my Author's copies of Paper Models that Rock. Thank you to Dover Publications who have done a great job with the book! 
The book contains six projects. Nodding Donkey, Flutter Box, Rockin' Robin, Rolling Bones, Tapping Feet and Wag the Dog. All are driven by pendulum power. I'll be putting together the models and making YouTube videos shortly, meanwhile I've uploaded a quick preview of the book itself onto YouTube.
