SYNOPSIS

interference [--display host:display.screen] [--visual visual]
[--window] [--root] [--window-id number] [--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

--root Draw on the root window.

--window-id number
Draw on the specified 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.
