| Description |
A cellular automaton consists of:
(a) A structure of cells, such as the squares on a chess board.
(b) A set of values or "states" such that each cell is associated with a particular state.
(c) A set of rules describing how one state of the system (a particular configuration of cells in specific states) is to be transformed or converted to another state of the system.
This is software for exploring five cellular automata, as follows:
1. An extended version of Conway's Life, called q-state Life.
2. A simulation of the Belousov-Zhabotinsky chemical reaction in which, beginning from a random state of the system, spirals and curlicues "spontaneously" emerge.
3. A process called Togetherness in which cells with random states move so as to maximize the number of neighbors of each cell in the same state as that cell (or, thought of in another way, in which the cells rearrange themselves so as to form maximal clusters of cells all having the same state).
4. Viral Replication, a simulation of a population of dividing cells subject to viral infection.
5. Diffusion-Limited Aggregation, illustrating a process in which particles diffuse (moving randomly) and aggregate to form a fractal structure.
The documentation provides a complete description of the algorithms used. |

Hermetic Systems
A program to search for eclipses (lunar, solar, total, annual and umbral), to calculate the phase of the Moon at any given date and time and to convert between dates in the Gregorian and Julian calendars and dates in various lunar calendars.
Easy Date Converter
8.37
Hermetic Systems
Adds a number of days to a date, calculates the number of days between two dates, and converts among Gregorian dates, Julian dates, Julian day numbers and ordinal dates of the form yyyy-ddd. Supports batch computation.
Easy Graphics File Converter
4.67
Hermetic Systems
Converts from GIF, JPG, PNG and BMP graphics files to JPG, PNG and BMP files. Allows single or multiple file conversion. Can convert to JPGs over a range of quality/compression values for optimization. Converted files displayed in your browser.
Data Destroyer
6.57
Hermetic Systems
A program for secure file deletion and disk wipe which destroys (by overwriting) data in multiple files and multiple folders on floppy, ZIP or hard disk so that the data cannot be recovered. Single-file or batch-mode operation.
Hermetic Word Frequency Counter
3.07
Hermetic Systems
This software scans a file, or text on the clipboard, and counts the number of occurrences of different words. The text can be in a language other than English. The words which are found and displayed can be ordered alphabetically or by frequency.
Keywords Meta Tag Generator

Hermetic Stego
5.17
Hermetic Systems
A steganography program which allows you to encrypt and hide a file of any size in BMP image files, with or without the use of a stego key, so that the presence of the hidden file is undetectable, even by software using statistical methods.
Chinese Calendrics
6.77
Hermetic Systems
A program to convert between dates in various Chinese calendars and dates in the Gregorian and Julian calendars, and to find lunar new year's day and leap months for any year in the Chinese Calendar.
Easy HTML Construction Kit
7.27
