Ezekiel is a trochoid explorer and designer.  Trochoids are
patterns drawn from wheels within rings (hypotrochoids) or
wheels around rings (epitrochoids).  The Spirograph(TM) designer
from the 1960s drew trochoids.  Ezekiel is Spirograph(TM) on
steroids!  This archive contains executables for 68020 Amigas
(or emulators) and AROS i386.  It includes example patterns and
some of my favorite designs.

Ezekiel starts off in illustration mode.  In this mode it randomly
draws trochoids and clears the screen with random special effects.
It's essentially a screen-saver.  Please watch for a while to get
an idea of what trochoids look like.  Some of my favorite patterns
were found just watching in Illustration mode.  Ezekiel saves a
default of 50 of the previous patterns drawn.  Ezekiel polls for
key strokes every tick except for some complex patterns where you
might have to wait for the pattern to finish before gaining
control.

From Illustration mode you can:
(d) goto Design mode
(s) Save the current screen as a bitmap
( ) pause drawing
(h, /, ?, or HELP) open a Help screen
(ESC) quit the program

Once you enter design mode you will be able to scroll (using the
arrow keys) through the default 50 previous patterns drawn in
history.  By default, info mode is on so that you can see the
design parameters used to draw and statistics about each pattern.

From Design mode you can:
(LEFT, DOWN) goto the previous pattern in the history
(RIGHT, UP) goto the next pattern in the history
(p) toggle Pattern type between hypotrochoids and epitrochoids
(r) enter the Ring radius
(w) enter the Wheel radius
(e) enter the pEn offset from the center of the wheel
(z) enter the step siZe (1 plots a point for each of 360 degrees
of wheel rotation)

(1-6) set the scale factor from 1 to 6
(7) enter a scale factor
(u) enter the number of revolUtions to plot (defaults to qty
required to close the pattern)
(q) revolution to start at (example 6 uses this to change colors
between different revolutions)
(o) use the mouse to set the pattern's origin
(j) enter degrees of rotation around origin to start the pattern
(x) use the mouse to set the origin of the tilt axis (see example
20)
(y) enter degrees of rotation around the tilt origin (see example
20)
(t) enter the numbers of seconds (Time) to display the graph
(changes plotting speed)
(g) enter a decimal rGb value for the color or one of the
predefined:
    BLACK
    MAROON
    GREEN
    OLIVE
    NAVY
    PURPLE
    TEAL
    GRAY
    SILVER
    RED
    LIME
    YELLOW
    BLUE
    PINK
    AQUA
    WHITE

(n) draw New pattern
(c) Copy current pattern
( ) pause drawing
(k) Kill (delete) the current pattern from history
(b) Behold centers and scales the pattern so it's all visible
(d) Draw or reDraw the current pattern
(m) toggle on/off Modification of the step size so that the pattern
closes on itself
(/ or ?) toggle display of the screen info on/off
(HELP) turn on screen info and redraw display
(a) toggle display of drawing aids (Axis) on/off
(s) Save screen as bitmap
(h) save History as an .ezk file for later viewing
(l) Load an .ezk history file for viewing
(v) toggle oVerlay mode on/off where scrolled patterns overlay each
other (examples 1-20)
(i) toggle Illustration mode
(ESC) quit program

The example drawer holds .ezk history files.  Most have png icons
which show what the finished pattern will look like.  The two
"favorites" files simply hold cool trochoids to view.  Examples
1-20, however, require use of oVerlay mode.  To view these:

1. Scroll RIGHT until you are at the last pattern in history.
2. Make room for loading additional patterns into history by
pressing "k" until you are at pattern #1.
3. Press "l" to load Example1.ezk into the history.
4. Goto pattern #2 (first loaded pattern).
5. Press "v" to enter overlay mode.
6. Wait for this pattern to finish drawing.
7. Scroll RIGHT to the next pattern and wait for it to finish
drawing.
8. Repeat step #7 until all patterns have been overlaid.
9. Ooh and ah.
10. Press "v" to exit overlay mode.
11. Goto step #2 to load another example file.

I hope that you enjoy this program as much as I have writing it
and using it.  Please let me know of any bugs or feature
requests.  Please share any .ezk files that you create so we can
all appreciate your creations.  You can contact me at the above
e-mail address.
