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, 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.

       -radius pixels
	       Radius of the spotlight in pixels.
