NAME
       starfish	- radially-symmetric throbbing colormap-hacking	graphics demo

SYNOPSIS
       starfish	 [-display  host:display.screen]  [-foreground	color] [-back-
       ground 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 de-
	       grees.)

       -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  sec-
	       onds.

       -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.
