NAME

       starfish - radially-symmetric throbbing colormap-hacking graphics demo

SYNOPSIS

       starfish  [-display host:display.screen] [-foreground color] [-background color] [-window]
       [-root] [-mono] [-install] [-visual visual]  [-delay  usecs]  [-delay2  secs]  [-thickness
       pixels] [-rotation degrees] [-duration seconds] [-colors int] [-blob] [-no-blob] [-fps]

DESCRIPTION

       The starfish program draws radially symmetric objects, which expand, contract, rotate, and
       turn inside out.  It uses these shapes to lay down a field  of  smooth  colors,  and  then
       rotates the colormap.

OPTIONS

       starfish 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.

       -delay microseconds
               How much of a delay should be introduced between steps of the animation.   Default
               10000, or about 1/100th second.

       -thickness pixels
               How  wide  each color band should be.  Default 0, meaning random (the chosen value
               will be between 0 and 15.)

       -rotation degrees
               How quickly the objects should rotate at each step.   Default  0,  meaning  random
               (the chosen value will be between 0 and 12 degrees.)

       -colors int
               How  many  colors  to  use.   Default  200.   The  more  colors,  the smoother the
               transitions will be, and the nicer the resultant images.

       -duration seconds
               How long to run before choosing a new shape.  Default 30 seconds.

       -delay2 seconds
               When duration expires, how long to wait before starting  a  new  run.   Default  5
               seconds.

       -blob

       -no-blob
               If blob option is specified, then the raw shapes will be shown, instead of a field
               of colors generated from them.

       -fps    Display the current frame rate and CPU load.

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.
