rorschach - simulate ink-blot patterns

rorschach [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-iterations integer] [-offset integer] [-xsymmetry] [-ysymmetry] [-erase-mode integer] [-erase-speed usecs] [-delay secs]

The rorschach program draws random patterns reminiscent of the psychological test of same name.

rorschach 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.

-iterations integer

How many dots should be drawn each time. Default 4000.

-offset integer

How far apart the dots should be. Default 4 pixels.

-xsymmetry

Whether the images should be horizontally symmetrical. Default true.

-ysymmetry

Whether the images should be vertically symmetrical. Default false.

-erase-mode integer

This sets the erase mode. Mode -1 chooses a random mode each time. There are currently 6 modes defined (0-5).

-erase-speed usecs

This controls the speed at which the screen will be erased. (Delay between erasing of individual lines.)

-delay seconds

This sets the number of seconds that the figure will be on the screen.

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.

May call your sanity into question.
