The starfish 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.

starfish accepts the following options:

--window

Draw on a newly-created window.  This is the default.

--root

Draw on the root window.

--window-id number

Draw on the specified window.

--mono

If on a color display, pretend we're on a monochrome display.

--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.

--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 degrees.)

--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 seconds.

--delay2 seconds

When duration expires, how long to wait before starting a new run. Default 5 seconds.

--blob

--no-blob

If blob option is specified, then the raw shapes will be shown,  instead of a field of colors generated from them.

--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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
