       bumps - move distorting spotlight around desktop


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


       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.


       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 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

       -delay microseconds
               Slow it down.

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

       -fps    Display the current frame rate and CPU load.


       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
