squiral accepts the following options:


Draw on a newly-created window.  This is the default.


Draw on the root window.


If on a color display, pretend we're on a monochrome display.


Install a private colormap for the window.

-visual visual

Specify which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

-fill percent

Specify the percent (0-100) of the screen which must be filled before the screen is cleared.  60-80 percent are good values.

-count number

The number of squiralies.  By default, the screen width divided by 32.

-delay usec

The wait between steps.  The default is 1000.

-disorder fraction

The fraction of the time a squiraly will choose a new direction. The default is 0.005.

-handedness fraction

The fraction of the time a squiraly will choose to enter lefthanded mode.  0.0 means exclusively right-handed behavior, 0.5 (the default) is a balance between the two, and 1.0 is exclusively left-handed behaviour.
