CBACK(1L) CBACK(1L) 1 June 1993 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. AUTHOR Rich Burridge richb@Eng.Sun.COM - 1 - Formatted: April 17, 2024
