       starfish - radially-symmetric throbbing colormap-hacking graphics demo

SYNOPSIS

       starfish  [--display  host:display.screen]  [--foreground color] [--background color] [--window] [--root]
       [--window-id number][--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.

       --window-id number
               Draw on the specified 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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
