NAME

       bumps - move distorting spotlight around desktop

SYNOPSIS

       bumps  [-display  host:display.screen]  [-foreground  color] [-background color] [-window]
       [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-duration secs] [-fps]

DESCRIPTION

       The bumps program takes an image and exposes small, distorted sections of it as if through
       an odd wandering spotlight beam.

       The  image  that  it manipulates will be grabbed from the portion of the screen underlying
       the window, or from the system's video input, or from a random file on disk, as  indicated
       by   the   grabDesktopImages,  grabVideoFrames,  and  chooseRandomImages  options  in  the
       ~/.xscreensaver file; see xscreensaver-demo(1) for more details.

OPTIONS

       bumps 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
               Slow it down.

       -duration seconds
               How long to run before loading a new image.  Default 120 seconds.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       XENVIRONMENT
