The slip program does lots of blits and chews up an image.

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-settings(1) for more details.


slip accepts the following options:


Draw on a newly-created window.  This is the default.


Draw on the root window.

--window-id number

Draw on the specified window.


If on a color display, pretend we're on a monochrome display.
