     [-no-cycle] [-blob] [-no-blob]

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 gen-
             erated 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_MANAGER
             property.
