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.
