If ThisNext were a book, it would be Gadget Nation. Many of the wacky fun products people put on ThisNext (Clocky, Octodog, cupcake cases, etc.) are featured in this book, along with some that probably haven't made it onto ThisNext yet. A great guide to some strange and wonderful inventions - makes a great gift or coffee table book.
This book totally expands your ideas about what a gadget is. Not just for geeks. Maybe design savvy geeks with a sense of humor, but still.
