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:
-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-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.
-fps Display the current frame rate and CPU load.


DISPLAY 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.
