I am amazed at how far book technology has come! My kids and I went to the bookstore today. My son got a pop-up Star Wars Guide to the Galaxy book that was absolutely unbelievable. Of course the price tag on that book was absolutely unbelievable too! Then my son found a Star Wars animation book. The characters in the illustrations actually looked like they were running. How do they make these things? Those illustrators must have some kind of paper engineering degree!
