DESCRIPTION¶
Floatbg is an X11 program that modifies the color of the root window in such a
manner that you won't see the color change, but after a while you'll notice
that it did change, however.
Floatbg starts with a random color and changes it deterministically by moving
through an hsv-model of colors. In the hsv-model, colors are described by
three parameters: Hue stands for the tint of a color (0 degrees is red, 60 =
yellow, 120 = green, 180 = aquamarine, etc), saturations stands for the
brightness of the color (0 = white, 1 = bright), and value stands for the
intensity of the color (0 = black, 1 = normal).
Every 10 seconds the hue (tint) is increased by one degree and the saturation
(brightness) is changed by a sinus over the hue. (The frequency of this change
can be adjusted with the -time parameter.) The shape of this sinus can be
adapted with the options -satmid, -satvar and -fase. The value (blackness) is
fixed and can be set with the option -value. The default values are:
floatbg -value .87 -satmid .375 -satvar .125 -fase .25, and are such
that all pastel tints are visited.
Extremely simplistic Gnome and Xfce support can be enabled with the
-gnome and
-xfce flags.
BUGS¶
Floatbg doesn't use any window, button or menu, and it can only be stopped by
killing it.
