NAME

       cwaves - languid sinusoidal colors

SYNOPSIS

       cwaves  [-display host:display.screen] [-foreground color] [-background
       color] [-window] [-root] [-mono] [-install]  [-visual  visual]  [-delay
       usecs] [-waves int] [-colors int] [-fps]

DESCRIPTION

       The  cwaves  program  draws  a  languidly-scrolling  vertical  field of
       sinusoidal colors.

OPTIONS

       cwaves 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 20000, or about 1/50th second.

       -waves int
               How  many  cosines  to  add together.  The more waves, the more
               complex the apparent motion.

       -colors int
               How many colors to use.  Default 800.   The  more  colors,  the
               smoother the blending will be.

       -fps    Display the current frame rate and CPU load.

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.
