folksy but conducive of thought crystallization . I found this book unsatisfactorily casual and slap-happy for the work of putative been-there-done-that expert with such lengthy tenure in and around things ufological. Yet, by reading this, I did manage to concretize a philosophical system that has been emerging for years as I read one UFO book after another--while also reading widely in other things paranormal, as well as a spate of less abstract fields, such as history, science, linguistics, anthropology, and such. Let us posit that aliens (1) exist; (2) have the technology to visit remote star systems; and (3) took greatly enhanced interest in earth only when it developed weapons systems capable of either harming other civilizations (i.e., in combination with its rocket technology) or of destroying itself (which would constitute a crying shame from the viewpoint of fundamentally beneficent aliens who respect other sentient life forms). Keyhoe leads me to believe--amid his conspiratorial musings and his subtle hints at what was meant by what was really meant by what Mr. X thought that Mr. Y intended--that they are watching us and executing a hands-off policy until such time that we pose a direct, immediate danger to ourselves (this will occur long before we pose a direct and immediate danger to exocivilizations), at which time--Starfleet-style "Prime Directives" od non-interference notwithstanding--they will take whatever steps are necessary to ensure the harmonious continuation of our culture. Whether that means utterly conquering and enslaving us, or surreptitiously seizing control over certain key organs of our governments (possibly to include forging certain elements of the whole-earth government whose existence Einstein endorsed as a logical and necessary eventuality), or just providing cultural "guidance counselors," who can really say. It is indeed food for thought to ponder the likely--well, the possible--archetypal alien ethos and surmise what it might intend for us and why it should, or will, occur when the time requires it

Cinema 4D 9.5 Excellent! well written, easy to follow. . This book has provided me with a hands on guid that I have search for many years. I am new to animation, and I think Mr. Mitchell did a fantastic job of explaining and making his real world application easy to follow. This book has taught me more about professional animation than any other books in my library. To me the CD is an added bonus. I would highly recommend this book to any beginner who is trying Learn 3D animation production. The only negative thing I have to say is, why it took you so long to publish a book that gave someone like me the confidence in learning 3D animation. I was able to create my first animated characters by using this book, by adding this book to your library, you will be gaining a wealth of knowledge. By the way, when is your next book coming out? Simply, this book is GREAT

There are better options . Unlike so many tutorial or reference books on the subject of Illustrator, this book only skims the surface of the key functions of Illustrator. Things to be aware of: There are no companion CD tutorials - you're on your own. This book does not give you detailed information on how to do anything. A few step-by-step examples are given on some certain methods, but mostly not. The few examples of "How to" are very high level and do not go into any detail. This book will not serve as a good reference book - information is to high level and does not include details. You will have to create your own graphics just to follow along the lessons so you can understand the concept. On the plus side: The book now has color illustrations. The tips on the bottom of each "How To" lesson are very useful. If you have a general knowledge of Illustrator, this book can be used without the software or a PC as casual reading. The book is broken down in seven parts: Part 1 - Prepare Your Illustrator Project Part 2 - Draw Objects Part 3 - Add Type Part 4 - Work with Drawings Part 5 - Manage Fills Part 6 - Use Layers and Styles Part 7 - From Illustrator to Print and Web This book borders on being useless for people who are seriious about learning Illustrator. Better books that will help the novice illustrator: Illustrator CS Hands-On Training by [...] books The Adobe Illustrator manual/book that comes with the software
