       This  draws  the  recursive  Hilbert  space-filling  curve, in both 2D and 3D variants.  It incrementally
       animates the growth and recursion to the maximum depth, then unwinds it back.

       The Hilbert path is a single contiguous line that can fill a volume without crossing itself.  As  a  data
       structure,  Hilbert  paths  are  useful  because ordering along the curve preserves locality: points that
       close together along the curve are also close together in space.  The converse is often, but not  always,
       true.  The coloration reflects this.

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.

       hilbert - 3D Hilbert fractal.

--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.

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --delaynumber
               Per-frame delay, in microseconds.  Default: 30000 (0.03 seconds.).

       --speednumber
               How fast the animation should run.  Less than 1 for slower, greater than 1 for faster.

       --max-depthnumber
               Max depth to descend.  Default: 5, which peaks at around half a million polygons.

       --spin--no-spin Whether to rotate the object.  Default: true.

       --wander--no-wander Whether to wander the object around on the screen.  Default: false;

       -2d-3d Whether to draw the 2D or 3D variant. Default: random.

       --closed--open Whether to draw the open or closed-path variant. Default: random.

       --thicknessratio
               How thick the lines should be.  Default: 0.25.

       --wireframe
               Render in wireframe instead of solid.

       --fps   Display the current frame rate, CPU load, and polygon count.
