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


kaleidescope accepts the following options:

Draw on the root window.
Draw on the specified window.
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.
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.
The number of segments to draw. Default is 7.
The number of trails to draw. Default is 100.
The rate at which segments rotate around their center. Default is -59.
The rate at which segments rotate around the center of the window. Default is 1.
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.
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.
