The green rectangle you will find at the center is the ruler
and the green circle with cogs is the hole (or "ring"). In the
you'll see a red gear (or "wheel"), with spirally arranged small
holes, in which you put the point of the pencil and roll about.
That means that you can place the pencil outside of the gear, specifically
on an auxiliary line extending from the center of the gear to the point
of the pencil. This line indicates the connection between the gear and
You have a means to let the gear roll about automatically:
By default "Auto Rotation" stops automatically when the gear returns
to where it started.
If you want to let the gear roll forever, uncheck "Stop rotating when walked around" on the Preferences panel (Other > Preferences > General).
It can take more than 100 turns to make a tour according to the combination
of gear and hole sizes.
There is an Easter Egg (an undocumented bit of code that is hidden inside an operating system) that will draw the complete tour at one time. (Hint: It's the keyboard character that appears in everyone's e-mail address!)
You can slide or rotate the ruler by dragging it with the mouse.
The number of cogs (or "teeth") on the gear (or "wheel") and the hole
(or "ring") are in proportion to their radius.
The number of cycles and characteristics of the pattern you draw are associated with the greatest common divisor (gcd) and least common multiple (lcm) of the numbers of cogs (or "teeth") on the gear (or "wheel") and the hole (or "ring").
The number of petals (or "cusps") is given by
If you want to specify the number of cogs, use the "Set by Data" option
(Control-T or Command-T) on the "Canvas" menu.
When the pattern's cycle is indicated as 5, the patterns that would be drawn are characterized by the number 5: a pentagon (five apexes), pentapetalous (five petals) flower, ranunculoid (five cusps), etc.
You can have this information appear at the bottom of window by choosing
"Show Info" (Control-I or Command-I) in the "Other" menu. **
Error: Windows info appears as gibberish **
If you want to erase only the last pattern, choose "Undo" (Control-Z
or Command-Z) from the "Edit" menu. You can Redo (Control-Shift-Z or Command-Shift-Z)
if it is executed immediately after the "Undo".
First select "Page setup" from the "File" menu and set up your printer. Then select "Print" (Control-P or Command-P) to send your pattern to your printer.
You can get the print-out of the pattern that you see on the screen, but because the printing resolution is generally higher than that of the screen, you will need to control the thickness of lines more precisely. You can adjust the "line thickness" on the "Print" tab of the Preferences panel (Other > Preferences > Print) by changing the number of points (pt).
Incidentally point (pt) is a unit of length, often used for the size of font, etc. 1pt is approximately 1/72 inch and 3pt corresponds to a little more than 1 mm. [Actually a point is equivalent to 1/72.27 inch, however most computer programs and systems adopt 1/72 inch.]
Before registration, you can print out only 1 pattern per window and a watermark "Spirographer DEMO" will print over the pattern.
The "Save" submenu is located in the "File" menu. To save the content of a window, choose Save" (Control-S or Command-S) from this submenu. The content will be saved in the original format (called SPG) which saves all information in the window and allows the file to be reopened for further use. SPG cannot be read by software other than Spirographer.
If you want to save the pattern in picture format, please choose from
"Save in PICT" (Command-1)(Mac Only) "Save in BMP" (Control-1)(Win Only) "Save in JPEG" (Control-2 or Command-2) "Save in EPSF" (Command-3)(Mac Only)in the "Save" submenu, in accordance with the intended use.
I have illustrated all the features of Spirographer above.
In next section, I will describe the Preferences panel, which allows you to use Spirographer more conveniently and comfortably.
The Preferences menu has four tabs:
|Disable startup screen
Doesn't show the startup dialog in which a small gear rolls about. Valid after registration.
Stop rotating when walked around
Stops the automatic rotation when the gear comes back to where it started. If it is turned off, the gear rolls forever.
No gear pattern
Doesn't show the spirally arranged small holes on the gear. This might prove useful once you get accustomed to the application.
Sets the default color of the pencil - adopted when the Spirograph window opens. You can set different colors for each design.
Sets the default background color - adopted when the Spirograph window opens.
Sets the color for the ruler.
Sets the color for the gear. The pattern on the gear will also be drawn in this color.
Auto coloring: Saturation
Sets the saturation level in Auto-coloring mode. When you move the slider to the left, the color becomes paler (more opaque). When you move the slider to the right, the color becomes deeper.
Auto Coloring: Brightness
Sets the brightness in Auto-coloring mode. When you move the slider to the left, the color becomes darker (more blackish). When you move the slider to the right, the color becomes brighter.
|(3) Sound (Mac Only)|
Changes the percussion instrument which makes the tick-tack.
Check if you don't want the hear the tick-tack.
|Line thickness (pt)
Changes the thickness of the line. Valid from 0.001pt to 10pt. This value affects all the design patterns which are displayed or printed.
I hope that you will enjoy Spirographer.
