NAME
       interference - decaying sinusoidal waves

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

DESCRIPTION
       Another color-field hack, this one works by computing decaying
       sinusoidal 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: 2.

       -delay number
               Per-frame delay, in microseconds.  Default: 30000 (0.03
               seconds.).

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

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

       -ncolors number
               Number of Colors.  Default: 192.

       -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.
