Overview
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.
-
--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
-
XENVIRONMENT -
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
-
XSCREENSAVER_WINDOW -
The window ID to use with --root.
