Paper Engineering at the Smithsonian

I'm sitting here in the Spark Lab at the Smithsonian's Museum of American History watching my son and his Cub Scout friends build things. We just saw Julia Child's kitchen and a wonderful exibit on Paper Engineering. It was a display of various styles and kinds of pop-up books. Some of them were standard pop-up books, but others were more elaborate carousels and panoramic shadow boxes. Suddenly I feel inspired. I think I want to construct something!
