DESCRIPTION

       The strange program draws strange attractors

OPTIONS

       strange 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.

       --ncolors integer
               How many colors should be used (if possible).  Default 100.  The colors are chosen
               randomly.

       --points integer
               Change  the number of points/iterations each frame.  Default 5500.  More than 6000
               activates the accumulator, which makes parts  of  the  image  brighter  or  darker
               depending on how often the attractor hits each pixel.

       --point-size integer
               Changes the size of individual points.  Default 1.

       --zoom float
               Zooms in or out.  Default 0.9.

       --brightness float
               Adjusts the brightness for accumulator mode.  Default 1.0.

       --motion-blur float
               Adds motion blur.  Default 3.0, no motion blur is 1.0.

       --fps   Display the current frame rate and CPU load.

ENVIRONMENT

       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.
