Q28a: What are some general references on fractals, chaos, and  
complexity?  
A28a: Some references are:  
  
M. Barnsley, _Fractals Everywhere_, Academic Press Inc., 1988. ISBN  
0-12-079062-9. This is an excellent text book on fractals. This is probably  
the best book for learning about the math underpinning fractals. It is also a  
good source for new fractal types.  
  
M. Barnsley and L. Anson, _The Fractal Transform_, Jones and  
Bartlett, April, 1993. ISBN 0-86720-218-1. This book is a sequel to  
_Fractals Everywhere_. Without assuming a great deal of technical knowledge,  
the authors explain the workings of the Fractal Transform (tm). The Fractal  
Transform is the compression tool for storing high-quality images in a  
minimal amount of space on a computer. Barnsley uses examples and  
algorithms to explain how to transform a stored pixel image into its fractal  
representation.  
  
R. Devaney and L. Keen, eds., _Chaos and Fractals: The Mathematics  
Behind the Computer Graphics_, American Mathematical Society,  
Providence, RI, 1989. This book contains detailed mathematical  
descriptions of chaos, the Mandelbrot set, etc.  
  
R. L. Devaney, _An Introduction to Chaotic Dynamical Systems_,  
Addison- Wesley, 1989. ISBN 0-201-13046-7. This book introduces  
many of the basic concepts of modern dynamical systems theory and leads  
the reader to the point of current research in several areas. It goes 
into great detail on the exact structure of the logistic equation and 
other 1-D maps.  The book is fairly mathematical using calculus and topology.  
  
R. L. Devaney, _Chaos, Fractals, and Dynamics_, Addison-Wesley,  
1990. ISBN 0-201-23288-X. This is a very readable book. It introduces  
chaos fractals and dynamics using a combination of hands-on computer  
experimentation and precalculus math. Numerous full-color and black and  
white images convey the beauty of these mathematical ideas.

recommended as an introduction. It introduces fractals from geometrical  
ideas, covers a wide variety of topics, and covers things such as time series  
and R/S analysis that aren't usually considered.

J. Pritchard, _The Chaos Cookbook: A Practical Programming Guide_,  
Butterworth-Heinemann, Oxford, 1992. ISBN 0-7506-0304-6. It contains  
type- in-and-go listings in BASIC and Pascal. It also eases you into 
some of the mathematics of fractals and chaos in the context of graphical  
experimentation. So it's more than just a type-and-see-pictures book, but  
rather a lab tutorial, especially good for those with a weak or rusty (or 
even nonexistent) calculus background.  
  
P. Prusinkiewicz and A. Lindenmayer, _The Algorithmic Beauty of  
Plants_, Springer-Verlag, NY, 1990. ISBN 0-387-97297-8. A very good

Books (subsidary of Henry Holt and Co.), New York. " ISBN 1-55851-  
298-5. This book describes a new method for generating beautiful fractal  
patterns by iterating simple maps and ordinary differential equations. It  
contains over 350 examples of such patterns, each producing a  
corresponding piece of fractal music. It also describes methods for  
visualizing objects in three and higher dimensions and explains how to  
produce 3-D stereoscopic images using the included red/blue glasses. The  
accompanying 3.5" IBM-PC disk contain source code in BASIC, C, C++,  
Visual BASIC for Windows, and QuickBASIC for Macintosh as well  
as a ready-to-run IBM-PC executable version of the program. Available for  
$39.95 + $3.00 shipping from M&T Books (1-800-628-9658).

R. Stevens, _Fractal Programming in C_, M&T Publishing, 1989  
ISBN 1-55851-038-9. This is a good book for a beginner who wants to  
write a fractal program. Half the book is on fractal curves like the Hilbert  
curve and the von Koch snow flake. The other half covers the Mandelbrot,  
Julia, Newton, and IFS fractals.

Q29: Are there any special notices?  
  
NOTICE (from Michael Peters):  
  
HOP - Fractals in Motion  
  
opens the door to a completely new world of fractals!  
  
Based on almost 30 new Hopalong type formulas and loads of incredible  
special effects, it produces an unlimited variety of images/animations  
quite unlike anything you have seen before.  
  
HOP features Fractint-like parameter files, GIF read/write,  
MAP palette editor, a screensaver for DOS, Windows, and OS/2, and more.  
Math coprocessor (386 and above) and SuperVGA required  
  
"HOP was originally based on HOPALONG, the Barry Martin creation which  
was popularized by A.K. Dewdney in one of his Scientific American  
articles. The HOP authors have taken Martin's idea well beyond his  
original concept, and developed it to such a degree that you need to keep  
reminding yourself of its modest beginnings. This program illustrates  
compellingly how a fundamentally simple idea can be extended, through the  
use of various graphics techniques, into something far removed from its  
humble origins. Don't let the simple name fool you - this is serious,  
robust, user friendly, IMAGINATIVE software !"

NOTICE from J. C. (Clint) Sprott (SPROTT@juno.physics.wisc.edu):  
  
The program, Chaos Data Analyzer, which I authored is a research and 
teaching tool containing 14 tests for detecting hidden determinism in a  
seemingly random time series of up to 16,382 points provided by the user in  
an ASCII data file. Sample data files are included for model chaotic  
systems. When chaos is found, calculations such as the probability  
distribution, power spectrum, Lyapunov exponent, and various measures of  
the fractal dimension enable you to determine properties of the system  
Underlying the behavior. The program can be used to make nonlinear  
predictions based on a novel technique involving singular value  
decomposition. The program is menu-driven, very easy to use, and even  
Contains an automatic mode in which all the tests are performed in succession  
and the results are provided on a one-page summary.  
  
Chaos Data Analyzer requires an IBM PC or compatible with at least 512K  
of memory. A math coprocessor is recommended (but not required) to  
Speed some of the calculations. The program is available on 5.25 or 3.5"  
disk and includes a 62-page User's Manual. Chaos Data Analyzer is peer-  
reviewed software published by Physics Academic Software, a cooperative  
Project of the American Institute of Physics, the American Physical Society,  
And the American Association of Physics Teachers.  
  
Chaos Data Analyzer and other related programs are available from The  
Academic Software Library, North Carolina State University, Box 8202,  
Raleigh, NC 27695-8202, Tel: (800) 955-TASL or (919) 515-7447 or  
Fax: (919) 515-2682. The price is $99.95. Add $3.50 for shipping in U.S.  
or $12.50 for foreign airmail. All TASL programs come with a 30-day,  
money-back guarantee.  
  
NOTICE from Noel Giffin (noel@erich.triumf.ca):  
  
Welcome to the Spanky Fractal Database   
  
This is a collection of fractal's and fractal related material for free  
distribution on the net. Most of the software was gathered from various  
ftp sites on the internet and it is generally freeware or shareware. Please  
abide by the guidelines set down in the individual packages. I would also  
like to make a disclaimer here. This page points to an enormous amount  
of information and no single person has the time to thoroughly check it  
all. I have tested software when I had the resources, and read through  
papers when I had the time, but other than certifying that it is related to  
fractals I can't assume any other responsibility.   
  
Enjoy and discover.
