       starfish - radially-symmetric throbbing colormap-hacking graphics demo


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


       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.


       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 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

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

       -cycle-delay microseconds
               How long to wait between shifting the  colormap  by  one  step.
               Default 100000, or about 1/10th 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

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


               Whether to do colormap cycling.  Default true.

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

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


               If blob option is specified, then the raw shapes will be shown,
               instead of a field of colors generated from them.


       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.
