29: Are there any special notices? (Fractal)

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 !"
(Jon Horner, editor, FRAC'cetera)

HOP is usually contained in a self-extracting HOPZIP.EXE file.
Places to download HOPZIP.EXE from:

Compuserve GRAPHDEV forum, lib 4
The Well under ibmpc/graphics
ftp.uni-heidelberg.de (under /pub/msdos/graphics)
spanky.triumf.ca [] (under pub.fractals.programs.ibmpc)

HOP WWW page: http://rever.nmsu.edu/~ras/hop

HOP mailing list: write to hop-request@acca.nmsu.edu

To subscribe to the HOP mailing list, simply send a message with the
word "subscribe" in the Subject: field. For information, send a message
with the word "INFO" in the Subject: field.

One thing that I forgot to mention about HOP is that it is contained in
the December issue of Jon Horner's FRAC'cetera magazine, and that
FRAC'cetera subscribers can register HOP for $20 instead of $30.

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.
