The intent of this book is to infuse the new-school Maker community with a therapeutic dose of slightly non-Euclidean engineering, classic shop techniques and surreally interpreted physics: projects intended to make people say “It does WHAT?” What’s not to love? These are projects with balls, albeit an uneven number of them. In a parallel universe, three doors down and across the street, these devices are de- facto standard office cube accessories, available at your local big box business supply outlet. Since we’re not fortunate enough to exist in such an enlightened timeline, we’re gonna have to build ’em ourselves. Remember, they laughed at Philo T. Farnsworth too.
