The kaleidescope program draws line segments in a symmetric
pattern that evolves over time.
kaleidescope accepts the following options:
- -root
- 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
- 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.
- -fps
- Display the current frame rate and CPU load.
- 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.
