NAME

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

SYNOPSIS

10       intermomentary  [-display  host:display.screen]   [-foreground   color]
11       [-background  color]  [-num-discs  disc  count]  [-draw-delay  delayms]
12       [-max-riders maxr] [-max-radius maxradius]

DESCRIPTION

15       The Intersection Momentary is a fun visualization  defining  the  rela‐
16       tionships  between  objects  with  Casey Reas, William Ngan, and Robert
17       Hodgin. Commissioned for display at the Whitney Museum of American Art.
18
19       A surface filled with 100 medium to small sized  circles.  Each  circle
20       has  a  different  size and direction, but moves at the same slow rate.
21       Display:
22
23           A. The instantaneous intersections of the circles.
24           B. The aggregate intersections of the circles.
25
26       The circles begin with a radius of 1 pixel and slowly increase to  some
27       arbitrary  size.   Circles are drawn with small moving points along the
28       perimeter. The intersections are rendered  as  glowing  orbs.   Glowing
29       orbs  are rendered only when a perimeter point moves past the intersec‐
30       tion point.

OPTIONS

36       intermomentary accepts the following options:
37
38       -num-discs disc count (Default: 85)
39               Number  of  slowly  moving  and growing discs to use.  The more
40               discs, the more CPU power.
41
42       -draw-delay delayms (Default: 30000)
43               Delay in ms between drawing cycles.  More  delay,  slower  (but
44               smoother and less CPU intensive.)  art.
45
46       -max-riders maxrider (Default: 40)
47               Maximum  number of 'riders', single dots moving around the edge
48               of the discs.
49
50       -max-radius maxradius (Default: 100)
51               Maximum possible radius of a disc.
52
53
54       ENVIRONMENT
55
56       DISPLAY to get the default host and display number.
57
58       XENVIRONMENT
59               to get the name of a resource file that  overrides  the  global
60               resources stored in the RESOURCE_MANAGER property.
61
62
63       BUGS
64
65       Setting the background to anything besides black confuses the intensity
66               algorithm and will look terrible.
