NAME
       fluidballs - the physics of bouncing balls.

SYNOPSIS
       fluidballs  [-display  host:display.screen] [-visual visual] [-window] [-root] [-count number] [-size number] [-gravity number] [-wind num-
       ber] [-elasticity number] [-delay number] [-nonrandom] [-no-shake] [-fps]

DESCRIPTION
       Models the physics of bouncing balls, or of particles in a gas or fluid, depending on the settings. If "Shake Box" is selected, then  every
       now and then, the box will be rotated, changing which direction is down (in order to keep the settled balls in motion.)

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.

       -count number
	       How many balls to display.  Default: 300.

       -size number
	       Maximum size of each ball.  Default: 25.

       -gravity number
	       Coefficient of gravity.	Useful values are < 0.1.  Default: 0.01.

       -wind number
	       Wind.  Useful values are < 0.1.	Default: 0.00.

       -elasticity number
	       Coefficient of elasticity.  Useful values are 0.2 to 1.0.  Default: 0.97.  Lower numbers make less bouncy balls.

       -delay number
	       Per-frame delay, in microseconds.  Default: 10000 (0.01 seconds.).

       -nonrandom
	       Make all balls be the same size.

       -no-nonrandom
	       Make the balls be random sizes.	Default.

       -shake | -no-shake
	       Whether to shake the box if the system seems to have settled down.  "Shake" means "change the direction of Down."

       -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.
