16 The Intersection Momentary is a fun visualization defining the relationships
17 between objects with Casey Reas, William Ngan, and Robert Hodgin. Commissioned
18 for display at the Whitney Museum of American Art.
20 A surface filled with 100 medium to small sized circles. Each circle has a
21 different size and direction, but moves at the same slow rate. Display:
23 A. The instantaneous intersections of the circles.
24 B. The aggregate intersections of the circles.
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

36 accepts the following options:
38 .B \-num\-discs \fIdisc count\fP (Default: \fI85\fP)
39 Number of slowly moving and growing discs to use. The more discs,
42 .B \-draw\-delay \fIdelayms\fP (Default: \fI30000\fP)
43 Delay in ms between drawing cycles. More delay, slower (but smoother
44 and less CPU intensive.)
47 .B \-max\-riders \fImaxrider\fP (Default: \fI40\fP)
48 Maximum number of 'riders', single dots moving around the edge of the discs.
50 .B \-max\-radius \fImaxradius\fP (Default: \fI100\fP)
51 Maximum possible radius of a disc.
55 Display the current frame rate and CPU load.
60 to get the default host and display number.
63 to get the name of a resource file that overrides the global
64 resources stored in the RESOURCE_MANAGER property.
69 Setting the background to anything besides black confuses the intensity
70 algorithm and will look terrible.
