NAME
       interference - decaying sinusoidal waves

SYNOPSIS
       interference  [-display host:display.screen] [-visual visual] [-window]
       [-root] [-count number] [-gridsize number] [-delay number] [-speed num‐
       ber]  [-radius  number]	[-ncolors  number] [-color-shift number] [-hue
       number] [-no-db] [-fps]

DESCRIPTION
       Another color-field hack, this one works by  computing  decaying	 sinu‐
       soidal  waves,  and allowing them to interfere with each other as their
       origins move.

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
	       Number of Waves.	 0 - 20.  Default: 3.

       -gridsize number
	       Magnification. 1 - 20.  Default: 4.

       -delay number
	       Per-frame delay, in microseconds.  Default:  30000  (0.03  sec‐
	       onds.).

       -speed number
	       Wave Speed.  1 - 100.  Default: 30.

       -radius number
	       Wave Size.  50 - 1500.	Default: 800.

       -ncolors number
	       Number of Colors.  Default: 128.

       -color-shift number
	       Color Contrast.	0 - 100.  Default: 60.

       -hue number
	       Hue  of	the  base  color (0-360, as in HSV space.)  Default 0,
	       meaning random.

       -db | -no-db
	       Whether to double buffer.

       -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.
