These are the 12 engineering projects that have been consuming my life for the past six months. But we're coming down to the deadline - the catalog has gone to print advertising the new book, so the creative part is over (always my favorite), and we're hashing out those pesky details like the intro, appendices, photos, etc. There are so many tedious little details you never think about when you first start to write a book. My favorite projects are the Ball Rocker (front center) and the Ping Pong Ball Levitator (back left).
