The deco program subdivides and colors rectangles randomly. It looks kind of like Brady-Bunch-era rec-room wall paneling. (Raven says: "This screensaver is ugly enough to peel paint.") Can also produce more aesthetically pleasing displays via options.

deco 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

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 seconds

How long to wait before starting over. Default 5 seconds.

-max-depth integer

How deep to subdivide. Default 12.

-min-width integer

-min-height integer

The size of the smallest rectangle to draw. Default 20x20.

-line-width integer

Width of lines drawn between rectangles. Default zero (minimal width).

-smooth-colors

-no-smooth-colors

Whether to use a smooth color palette instead of a random one. Less jarring. Default False.

-golden-ratio

-no-golden-ratio

Whether to subdivide rectangles using the golden ratio instead of 1/2. This ratio is supposed to be more aesthetically pleasing. Default false.

-mondrian

-no-mondrian

Whether to imitiate style of some famous paintings by Piet Mondrian. Overrides line-width and colormap options. Default false.

-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.
