These are a few of the programs I have written for the Amiga computer.
I don't update this page often enough to avoid link rot, so I don't link to any of these.
If you still have an Amiga or an emulator and would like to try some of these,
just search the web, many are out there in someone's database.

PowerLOGO

A powerful and versatile dialect of the LOGO programming language.
It is a very high level language, easy to use, and easy to learn. Yet it
has some low level power as well.
It uses the simplest subset of LOGO syntax, and is defined by
the simplest rules.
It includes all of the support for word and list
processing, program code processing, local variables, global
variables, free variables, recursion, tail recursion, ...
that you expect from LOGO. Also includes support for demons,
while loops, menus, screens, windows, window graphics,
turtle graphics, reading and writing files, optional inputs
for procedures, ARexx, ... Release 1.4.

Slicer 2

Slicer is a program for creating fractal art based on mathematical
functions, such as the Mandelbrot set, Julia sets, and related abstractions
(chaotic dynamical systems). Features include; fast fixed or floating point
arithmetic, many different functions
(z^{2}+c, z^{3}3a^{2}z+b, sin(z) ...),
many
computation options (level sets, binary decomposition, epsilon cross,
distance estimate), many coloring and rendering options, images may be
recolored without recomputing, batch mode, focus, multi pass, zoom in, zoom
out, pan, quick 2x zoom, and four dimensional navigation. The program is
named "Slicer" because the pictures it makes can be thought of as cross
sections or "slices" revealing the insides of solid (if imaginary) objects.
I wrote a set of programs that replace Slicer for making some
fractals.
Each has its own fractal creation section, and they all have similar
image processing sections.

ZSquared

Creates fractal pictures based on the complex function
z=z^{2}+c
(the Mandelbrot set).

SineZ

Creates fractal pictures based on the complex sine of Z.

CosineZ

Creates fractal pictures based on the complex cosine of Z.

ZPower4

Creates fractal pictures based on the complex function
z=z^{3}3a^{2}z+b.

Chaos

Creates fractal pictures from Iterated Function Systems (the chaos game).
Includes a graphical user interface based on the collage theorem.

Paranoids

The Asylum Escape Game.
Paranoids is a traditional board game for two to four players.
Played by drawing cards, rolling
dice and moving pieces around the board. Each player has six pieces four
patients and two doctors. The object of the game is to get all of your
patients out of the asylum.
Based on the original board game by Richard Anderson.

Gravity Well

Celestial Motion Simulator.
Gravity Well simulates the motion of up to twenty bodies in Newton's
universe.
The
position, velocity and mass of each body may be entered with the mouse or
by typing the numbers into the boxes in the data window and clicking the
enter button.
The view of the simulation may be scaled, rotated in three
dimensions or repositioned using the buttons in the view control window.

RPSC

Reverse Polish Scientific Calculator.
A programmable reverse polish notation calculator.
It supports real numbers, complex numbers,
matrices, 3D vectors,
labeled variables,
Numerical integration,
Numerical solve.

TurMite

A two dimensional Turing machine simulator.
This creates colorful constantly changing pictures.
Imagine a small bug crawling around on your computer display moving one
pixel at a time. At each step it uses its internal state number and the
color of the pixel its on as indexes into a set of tables to decide what
color to change the pixel to, what direction to move, and what its new
internal state should be.
