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-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.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
