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.

       -cycle-delay microseconds
               How long to wait between shifing 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 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.

       -cycle

       -no-cycle
               Whether to do colormap cycling.  Default true.

       -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 gener-
               ated from them.

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_MAN-
               AGER property.
