NAME

       floatbg - slowly modify the color of the X root window

SYNTAX

       floatbg [-display display] [-help] [-gnome] [-xfce] [-value float] [-satmid float] [-satvar float] [-fase float] [-time float]

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), sat-
       urations 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 fre-
       quency 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.

NAME

       hypercube - 2d projection of a 4d object

SYNOPSIS

       hypercube  [-display  host:display.screen]  [-foreground color] [-background color] [-color[0-7] color] [-xy float] [-xz float] [-yz float]
       [-xw float] [-yw float] [-zw float] [-observer-z int] [-delay usecs] [-window] [-root] [-mono] [-install] [-visual visual]

DESCRIPTION

       The hypercube program displays a wireframe projection of a hypercube which is rotating at user-specified rates around any  or  all  of  its
       four axes.

OPTIONS

       hypercube accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -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.

       -delay microseconds
	       How much of a delay should be introduced between steps of the animation.  Default 100000, or about 1/10th second.

       -observer-z int
	       How far away the observer is from the center of the cube (the cube is one unit per side.)  Default 5.

       -color0 color

       -color1 color

       -color2 color

       -color3 color

       -color4 color

       -color5 color

       -color6 color

       -color7 color
	       The  colors used to draw the line segments bordering the eight faces of the cube.  Some of the faces have only two of their border-
	       lines drawn in the specified color, and some have all four.

       -xw float

       -xy float

       -xz float

       -yw float

       -yz float

       -zw float
	       The amount that the cube should be rotated around the specified axis at each frame of the animation, expressed in  radians.   These
	       should be small floating-point values (less than 0.05 works best.)  Default: xy=0.01, xz=0.005, yw=0.01.

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.
