NAME

       piecewise - lots of moving circles intersecting in interesting ways.

SYNOPSIS

       piecewise  [--display  host:display.screen]  [--visual  visual]  [--window] [--root] [--window-id number]
       [--delay  number]  [--count  number]  [--ncolors  number]  [--colorspeed  number]  [--minradius   number]
       [--maxradius number] [--no-db] [--fps]

DESCRIPTION

       This draws a bunch of moving circles which switch from visibility to invisibility when they intersect.

OPTIONS

       --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.

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

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --delay number
               Per-frame delay, in microseconds.  Default: 5000 (0.01 seconds.).

       --count number
               Number of circles.  Default: 32.

       --ncolors number
               Number of colors, only one of which is used at a time.  Default: 256.

       --colorspeed number
               How fast the color changes (0 - 100).  Default: 10.

       --minradius number
               Minimum circle radius (as a proportion of screen height). Default: 0.05.

       --maxradius number
               Maximum circle radius (as a proportion of screen height). Default: 0.2.

       --db | --no-db
               Whether to double buffer.

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

ENVIRONMENT

       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.
