The Intersection Momentary 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.
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 intersec-

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.
DISPLAY to get the default host and display number.

global resources stored in the RESOURCE_MANAGER prop-
Setting the background to anything besides black confuses the
algorithm and will look terrible.
