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.

--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 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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
