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] [-radius pixels]

DESCRIPTION
       The  bumps  program takes an image and exposes small, dis-
       torted sections of it as if through an odd wandering spot-
       light 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(o) 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.

       -radius pixels
               Radius of the spotlight in pixels.

ENVIRONMENT

               the  global  resources stored in the RESOURCE_MAN-
               AGER property.
