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.

       --window-id number
               Draw on the specified 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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
