NAME

       intermomentary - Visualize the momentary and aggregate intersections between slowly moving
       circles.

SYNOPSIS

       intermomentary  [--display  host:display.screen]  [--visual  visual]  [--window]  [--root]
       [--window-id  number]  [--foreground  color] [--background color] [--num-discs disc count]
       [--draw-delay delayms] [--max-riders maxr] [--max-radius maxradius] [--fps]

DESCRIPTION

       The Intersection Momentary is a  fun  visualization  defining  the  relationships  between
       objects  with Casey Reas, William Ngan, and Robert Hodgin. Commissioned for display at the
       Whitney Museum of American Art.

       A surface filled with 100 medium to small sized circles. Each circle has a different  size
       and direction, but moves at the same slow rate. Display:

           A. The instantaneous intersections of the circles.
           B. The aggregate intersections of the circles.

       The  circles  begin  with  a radius of 1 pixel and slowly increase to some arbitrary size.
       Circles are drawn with small moving points along  the  perimeter.  The  intersections  are
       rendered  as  glowing  orbs.   Glowing orbs are rendered only when a perimeter point moves
       past the intersection point.

OPTIONS

       Intermomentary accepts the following options:

       --num-discs disc count (Default: 85)
               Number of slowly moving and growing discs to use.  The more discs,  the  more  CPU
               power.

       --draw-delay delayms (Default: 30000)
               Delay in ms between drawing cycles.  More delay, slower (but smoother and less CPU
               intensive.)  art.

       --max-riders maxrider (Default: 40)
               Maximum number of 'riders', single dots moving around the edge of the discs.

       --max-radius maxradius (Default: 100)
               Maximum possible radius of a disc.

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

       --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.

BUGS

       Setting the background to anything besides black confuses the intensity algorithm and will
       look terrible.

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.
