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


        interaggregate  [-display  host:display.screen]   [-foreground   color]
        [-background  color]  [-num-circles disc count] [-growth-delay delayms]

        The  Intersection  Aggregate  is a fun visualization defining the rela-
        tionships 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.
            A. The instantaneous intersections of the circles.
            B. The aggregate intersections of the circles.

        interaggregate accepts the following options:
        -num-circles disc count (Default: 100)
                Number  of  slowly  moving  and growing discs to use.  The more
                discs, the more CPU power.
        -growth-delay delayms (Default: 18000)
                Delay in ms between drawing cycles.  More  delay,  slower  (but
                smoother and less CPU intensive.)  art.
        -fps    Display the current frame rate and CPU load.


        DISPLAY to get the default host and display number.
                to  get  the  name of a resource file that overrides the global
                resources stored in the RESOURCE_MANAGER property.
        Setting the background to anything besides black confuses the intensity
                algorithm and will look terrible.
