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

34 Intermomentary accepts the following options:
35
36 --num-discs disc count (Default: 85)
37 Number of slowly moving and growing discs to use. The more
38 discs, the more CPU power.
39
40 --draw-delay delayms (Default: 30000)
41 Delay in ms between drawing cycles. More delay, slower (but
42 smoother and less CPU intensive.) art.
43
44 --max-riders maxrider (Default: 40)
45 Maximum number of 'riders', single dots moving around the edge
46 of the discs.
47
48 --max-radius maxradius (Default: 100)
49 Maximum possible radius of a disc.
50
51 --fps Display the current frame rate and CPU load.
52
53 --visual visual
54 Specify which visual to use. Legal values are the name of a
55 visual class, or the id number (decimal or hex) of a specific
56 visual.
57
58 --window
59 Draw on a newly-created window. This is the default.
60
61 --root Draw on the root window.
62
63 --window-id number
64 Draw on the specified window.
65
67 Setting the background to anything besides black confuses the intensity
68 algorithm and will look terrible.
69
71 DISPLAY to get the default host and display number.
72
73 XENVIRONMENT
74 to get the name of a resource file that overrides the global
75 resources stored in the RESOURCE_MANAGER property.
76
77 XSCREENSAVER_WINDOW
78 The window ID to use with --root.
