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, grabVide‐
       oFrames,	 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.
