       Packs  the  screen with growing boxes or circles, colored according to a horizontal or vertical gradient.
       The objects grow until they touch, then stop.  When the screen is full, they shrink away and the  process
       restarts.

DISPLAY to get the default host and display number.

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

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

       boxfit - fills space with a gradient of growing boxes or circles.

--visualvisual
               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.

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --delaymicroseconds
               How much of a delay should be introduced between steps of the animation.  Default 20000, or about
               0.02 seconds.

       --countint
               How many boxes or circles to animate simultaneously; default 50.  Smaller  numbers  yield  larger
               boxes/circles.

       --growbyint
               How many pixels the objects should grow by, each frame.  Default 1.

       --spacingint
               How many pixels of space should be left between the objects.  Default 1.

       --borderint
               Thickness of the colored border around each object.  Default 1.

       --circles|--squares|--random
               Draw circles, squares, or choose randomly (the default).

       --grab  Normally  it colors the boxes with a horizontal or vertical gradient.  If --grab is specified, it
               will instead load a random image, and color the boxes according to the colors in that image.   As
               the picture fills in, some features of the underlying image may become recognisable.

               When  grabbing  images,  the  image 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.

       --peek  This option says to briefly show you the underlying image before beginning.  The default  is  not
               to show the unadulterated image at all.  (This only has an effect when --grab is used.)

       --fps   Display the current frame rate and CPU load.
