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.
-mono If on a color display, pretend we’re on a monochrome display.
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
How much of a delay should be introduced between steps of the
animation. Default 10000, or about 1/100th second.
How wide each color band should be. Default 0, meaning random
(the chosen value will be between 0 and 15.)
How quickly the objects should rotate at each step. Default 0,
meaning random (the chosen value will be between 0 and 12
How many colors to use. Default 200. The more colors, the
smoother the transitions will be, and the nicer the resultant
How long to run before choosing a new shape. Default 30
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 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.
