NAME
       hydrostat - Wiggly squid	or jellyfish with many tentacles.

SYNOPSIS
       hydrostat  [-display  host:display.screen]  [-visual  visual] [-window]
       [-root] [-delay number] [-speed number] [-count	number]	 [-head-radius
       number]	 [-tentacles  number]  [-thickness  number]  [-length  number]
       [-gravity number]  [-current  number]  [-friction  number]  [-no-pulse]
       [-wireframe] [-fps]

DESCRIPTION
       Wiggly squid or jellyfish with many tentacles.  A muscular hydrostat is
       a biological structure used to move its host about, consisting of  mus-
       cles with no skeletal support. It performs its hydraulic	movement with-
       out fluid in a separate compartment, as in a hydrostatic	skeleton.

OPTIONS
       -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.

       -window Draw on a newly-created window.	This is	the default.

       -root   Draw on the root	window.

       -delay number
	       Per-frame delay,	in microseconds.  Default:  20000  (0.02  sec-
	       onds).

       -speed number
	       Animation  speed.   2.0	means twice as fast, 0.5 means half as
	       fast.

       -count number
	       Number of squid.	 1 - 100.  Default: 10.

       -head-radius number
	       Head size.  10 -	100.  Default: 60.

       -tentacles number
	       Number of tentacles.  3 - 100.  Default:	40.

       -thickness number
	       Thickness of tentacles.	3 - 40.	 Default: 18.

       -length number
	       Length of tentacles.  10	- 150.	Default: 70.

       -gravity	number
	       Strength	of gravity.  0 - 10.0.	Default: 0.5.

       -current	number
	       Strength	of current.  0.0 - 10.0.  Default: 0.25.

       -friction number
	       Coefficient of friction.	 0.0 - 0.1.  Default: 0.02.

       -pulse |	-no-pulse
	       Whether the squid should	pulse. Default true.

       -wireframe | -no-wireframe
	       Render in wireframe instead of solid.

       -fps | -no-fps
	       Whether to show a frames-per-second display at  the  bottom  of
	       the screen.

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.
