Beautiful Designs

Looking for the next level of coloring book with abstract patterns never seen before? Here it is!

This unique coloring book presents 37 mathematically created patterns of ornate beauty, from large swirly spaces to delightfully delicious details. These designs will ignite your creativity and reduce the stress of this year with a breath of fresh air.

Here are some small fun books I am creating. They are locally printed limited editions, and are only from a local shop or two here in my home-town of Bellingham, Washington USA. I don't mail them, but can hand you a copy if you are in the area.

Ray Tracing for the Macintosh/CD - (out of print)

Paperback book, Published 1994, by Waite Group Press (info here)

(Copies of this book sometimes show up at discount book centers, and you may still be able to find it on-line... Click book cover above to search for it on Amazon.)

My (now out-of-print) tutorial book "Ray Tracing for the Macintosh CD" shows you how to create your own photo-realistic computer images, with free software for Mac, Windows, Linux, etc. The book comes with a Mac OS (9) CD-ROM that has the full POV-Ray Macintosh application & documentation, lots of scenes with sources from professional artists, animated QuickTime movies, an on-line multimedia encyclopedia of POV-Ray keywords, many Mac utility programs, etc. The book starts at an introductory level, giving an overview of ray tracing and 3-D art. It then explains POV-Ray, its language, and starts you building scenes. It has a chapter on advanced scene design and creation. There is a chapter on creating QuickTime animations, with tips on how to move things around in your scene. There are many example movies on the CD-ROM, and tools to create QuickTime movies yourself. This book covers POV-Ray Mac OS version 2.2, but the techniques and examples in the book carry over to POV-Ray version 3, as well as other rendering applications.

About the Author

For Fun

My first lifetime was spent in San Diego California, USA, attending UCSD and National University and collecting a Bachelor of Science degree in computer science, writing various kinds of software including educational, language translation, tax preparation, and video/photo editing, as well as raising 2 children and a cat, and publishing a computer graphics book.

Now I am enjoying my second lifetime with my wife and the eagles and owls in the forests at the top of Washington State. I am busy writing my own software and books, composing music, making music videos, photographing wildlife, home-roasting my own coffee, traveling, exploring, and still learning and creating new things every day.
