Kaleidescope — rotating line segments


kaleidescope [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-install] [-visual visual] [-color_mode mono | nice | greedy] [-nsegments int] [-ntrails int] [-local_rotation int] [-global_rotation int] [-delay usecs] [-redmin int] [-greenmin int] [-bluemin int] [-redrange int] [-greenrange int] [-bluerange int] [-fps]


The kaleidescope program draws line segments in a symmetric pattern that evolves over time.


kaleidescope accepts the following options:


Draw on the root window.

-color_mode mono | nice | greedy

Specify how kaleidescope uses colors. Mono uses just the default foreground and background colors. Nice uses one color for each segment (specified by nsegments). Greedy uses (ntrails * nsegments) + 1  colors.


Install a private colormap for the window.

-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.

-nsegments integer

The number of segments to draw. Default is 7.

-ntrails integer

The number of trails to draw. Default is 100.

-local_rotation integer

The rate at which segments rotate around their center. Default is -59.

-global_rotation integer

The rate at which segments rotate around the center of the window. Default is 1.

-redmin, -greenmin, -bluemin, -redrange, -greenrange, -bluerange

All take an integer argument. When colors are randomly chosen, they  are chosen from the interval min to min plus range. The minimums default to 30000. The ranges default to 20000.

-delay microseconds

How much of a delay should be introduced between steps of the animation. Default is 20000, or about 5 frames a second.


Display the current frame rate and CPU load.



to get the default host and display number.


to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
