program draws radially symmetric objects, which expand,
contract, rotate, and turn inside out. It uses these shapes to lay down a
field of smooth colors, and then rotates the colormap.
accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- If on a color display, pretend we're on a monochrome
- 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.
- -delay microseconds
- How much of a delay should be introduced between steps of
the animation. Default 10000, or about 1/100th second.
- -thickness pixels
- How wide each color band should be. Default 0, meaning
random (the chosen value will be between 0 and 15.)
- -rotation degrees
- How quickly the objects should rotate at each step. Default
0, meaning random (the chosen value will be between 0 and 12
- -colors int
- How many colors to use. Default 200. The more colors, the
smoother the transitions will be, and the nicer the resultant images.
- -duration seconds
- How long to run before choosing a new shape. Default 30
- -delay2 seconds
- When duration expires, how long to wait before
starting a new run. Default 5 seconds.
- If blob option is specified, then the raw shapes
will be shown, instead of a field of colors generated from them.
- 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.
