/news.archive
This directory contains all the articles ever posted on the Forum. They are in directories according to where they were posted. They are listed only by article number. An enclosed index lists the articles by Subject heading and article number for easier searching.
** Eventually, we will have different topics archived together as well. A project in progress. Look for this starting July 1.

/pictures
The contents of this folder are Postscript documents that can be downloaded and sent to a Postscript printer or viewed with a PS viewer (such as the NeXT or Ghostscript on the Mac). The contents of this folder will often be quite large, and we'll try to provide a size in the info file for each entry.

/projects
The files listed in this directory are abstracts, or descriptions, of projects taking place that are working in the field of goemetry and high school math in general. The sources of these abstracts are varied. Most titles are followed by a short code indicating the source. For example, those titles followed by .NSF have been sponsored by the National Science Foundation. The listing below also indicated where the project is taking place. Note: some of these projects have expired, but information may still be available.

/software/mac
1d.explorer.sea.hqx Program for exploring chaotic behavior of functions on the real line. Shareware ($5 or $10 fee).
fractal.wizard1.6.sea.hqx Color fractal drawing program. Allows saving pictures as PICTs, and it is also possible to write your own modules that draw other kinds of fractals. Full source code is included. Freeware.
hyp.flight.sim.sea.hqx This program lets you fly around in various manifolds, such as the 3 torus, projective 3space, and some manifolds with hyperbolic geometries. The hyperbolic ones look best on a pretty fast Mac. Freeware.
hyp.macdraw1.0.sea.hqx Lets you draw points, lines and polygons in the Poincare' disk, Klein disk or Poincare' halfplane models of the hyperbolic plane. Freeware.
hypercube1.0.sea.hqx Displays pictures of a rotating hypercube. You control the rates of rotation around the various axes, and the perspective of the view. Freeware.
hypergeo.sea.hqx Draws pictures of semiregular tilings of the hyperbolic plane. This is a prototype and is somewhat rough. Freeware.
hyperspace2.0.sea.hqx Displays pictures of various 3 and 4dimensional polyhedra. Freeware.
ifs.movie.sea.hqx Displays a movie of a fractal deforming. Freeware.
julias.dream1.07.sea.hqx Very fast Juliaset drawer. Freeware.
mandella8.6.sea.hqx Color Mandelbrot set (and other fractals too) explorer. Saves pictures in several formats. Includes lots of sample images. Shareware ($40 fee).
mandelscope.maker1.0.sea.hqx this file contains the programs MandelScope and MandelMaker. MandelScope is a Mandelbrot set explorer and MandelMaker is a Mandelbrot image generator. You use MandelScope to find a place you like and then use MandelMaker to generate an image and save it as a PICT. MandelMaker is freeware and MandelScope is $10 shareware.
** mandelzot4.0.sea.hqx (updated from 3.0.4) Color Mandelbrot set explorer. Freeware.
reptiles1.5.sea.hqx Program for drawing tilings of the Euclidean plane. The program is based on the theory of DelaneyDress symbols, and includes a DD symbol editor. Also includes lots of sample tilings. Draws in color. Shareware ($30 fee).
super.mandelzoom1.06.sea.hqx Black & white Mandelbrot set explorer. Very fast, but does not support saving pictures. Sort of shareware (no fee specified).
wallpaper1.1.sea.hqx Draws cool patterns based on function iteration. Freeware.

/software/pc
dysyst.zip Program for exploring Newton's method for roots of polynomials in the complex plane, the Mandelbrot set, and Julia sets. Allows multiple simultaneous color images. Requires a 386 or 486 with a math coprocessor and Windows. You must ftp this file in BINARY mode (check the instructions for your ftp program to see how to do this). WARNING: We do not have a PC here and were thus not able to check this program for viruses. Please check it as soon as you download it!
penrose/ This directory contains two files: PENROS.ZIP and README. PENROSE.SCR is an AutoCAD script file for generating Penrose tile arrangements of arbitrary size. You must have AutoCAD release 11 or higher to use it. This material was written by Bradley Austin and is public domain.
