It has been five years since I started to write this book. It includes the things that let me contemplate and think reversely for the past twenty years. One hundred and thirty four stories were written about my observations and reflections of the technologies. To use Dickens' words: "With technologies, we were all going direct to Heaven. With technologies, we were all going direct the other way." With this book, I hope to make a remark on my tech art creations.
