## NAME

squiral - square spirals screensaver

## SYNOPSIS

**squiral** \[-display *host:display.screen*\] \[-foreground *color*\] \[-background *color*\] \[-window\] \[-root\] \[-mono\] \[-install\] \[-noinstall\] \[-visual *visual*\] \[-fill *percent*\] \[-count *number*\] \[-delay *usec*\] \[-disorder *fraction*\] \[-handedness *fraction*\] \[-cycle\]

## DESCRIPTION

The *squiral* program displays interacting, spiral-producing automata

## OPTIONS

*squiral* accepts the following options:

- **-window**

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

- **-root**

  Draw on the root window.

- **-mono**

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

- **-install**

  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.

## ENVIRONMENT

- **DISPLAY**

  to get the default host and display number.

- **XENVIRONMENT**

  to get the name of a resource file that overrides the global resources stored in the RESOURCE\_MANAGER property.
