NAME
intermomentary - Visualize the momentary and aggregate intersections between slowly moving circles. SYNOPSIS
intermomentary [-display host:display.screen] [-foreground color] [-background color] [-num-discs disc count] [-draw-delay delayms] [-max-riders maxr] [-max-radius maxradius] [-fps] DESCRIPTION
The Intersection Momentary is a fun visualization defining the relationships between objects with Casey Reas, William Ngan, and Robert Hod- gin. 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. Display: 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 inter- section point. Ported to XScreensaver from the art project "InterMomentary" at http://www.complexification.net by J.Tarbell OPTIONS
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. ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. BUGS Setting the background to anything besides black confuses the intensity algorithm and will look terrible. SEE ALSO

NAME
MetaBalls - draws 2D metaballs SYNOPSIS
MetaBalls [-display host:display.screen] [-visual visual] [-window] [-root] [-ncolors number] [-count number] [-delay number] [-cycles num- ber] [-radius number] [-delta number] [-fps] DESCRIPTION
This hack draws 2D metaballs to the screen by calculating the sum of the colors of all metaballs covering a pixel. Ported from the demo effects collection (http://demo-effects.sourceforge.net) OPTIONS
-visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. -window Draw on a newly-created window. This is the default. -root Draw on the root window. -ncolors number Number of Colors. Default: 256. -count number Number of MetaBalls. 2 - 255. Default: 10. -delay number Per-frame delay, in microseconds. Default: 5000 (0.005 seconds.). -cycles number Duration. 100 - 3000. Default: 1000. -radius number MetaBall Radius. 2 - 100. Default: 100. -delta number MetaBall Movement. 1 - 20. Default: 3. -fps Display the current frame rate and CPU load. ENVIRONMENT
DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. SEE ALSO
