NAME
cback - a random color background generator
SYNOPSIS
cback [ -c ] [ -d display ] [ -p period ] [ -s ] [ -v ] [ -w ]
DESCRIPTION
Cback is a random color background generator that uses X11 graphics.
Currently there are three different styles of random backgrounds:
Circles The size, thickness, color, position and number of
the circles are all random.
Squares The size and color of the squares are random.
Wallpaper Various seed factors are random. The random squares
was inspired by a Mondrian picture generator by
James Gosling. The random circles was based on a
program written for the Perq by Nigel Bond in 1983.
The wallpaper patterns are based on a Computer
Recreation column by A. K. Dewdney in Scientific
American.
OPTIONS
-c Generate random colored circles.
-d display
Used to give a display type.
-p period
Give a period in seconds for the next random redraw. The default
is 300 seconds (5 minutes).
-s Generate random colored squares (the default).
-v Print the version number of this release of the cback program.
-w Generate random wallpaper patterns.
BUGS
Cback should be a little more clever about color. Too many "black"
shades are currently being generated.
