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

       strange - draws strange attractors

strange accepts the following options:

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

       --root  Draw on the root window.

       --window-idnumber
               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.

       --visualvisual
               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.

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

       --pointsinteger
               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-sizeinteger
               Changes the size of individual points.  Default 1.

       --zoomfloat
               Zooms in or out.  Default 0.9.

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

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

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