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.
