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


SYNOPSIS
       intermomentary  [-display  host:display.screen]  [-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.


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.

       BUGS

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