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-speed usecs] [-delay secs] [-fps]


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


rorschach 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.
-iterations integer
How many dots should be drawn each time. Default 4000.
-offset integer
How far apart the dots should be. Default 4 pixels.
Whether the images should be horizontally symmetrical. Default true.
Whether the images should be vertically symmetrical. Default false.
-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 the current frame rate and CPU load.


to get the default host and display number.
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.
