       jigglypuff - save your screen by tormenting your eyes.


       jigglypuff  [-display  host:display.screen]  [-visual visual] [-window]
       [-root] [-delay number] [-cycles number]  [-wireframe]  [-fps]  [-color
       colorspec] [-spooky] [-complexity n] [-speed n] [-spherism n] [-hold n]
       [-distance n] [-damping n]


       This draws all manners of obscene, spastic, puffy, vaguely  ball-shaped
       objects  orbiting  lazily  about  the  screen, with a dizzying array of
       mostly pointless options.


       -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

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

       -root   Draw on the root window.

       -delay number
               Per-frame  delay,  in  microseconds.   Default:   20000   (0.02

               Render in wireframe instead of solid. Default: render solid.

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

       -tetra | -no-tetra
               Whether  to  start  the shape in the form of a tetrahedron. The
               default is to start as a sphere.

       -color colorspec
               Available  options  for  colorspec   are:   cycle,   flowerbox,
               clownpuke,  chrome  and  #xxxxxx  (i.e  an  (old-style) X color
               specification.) Default: cycle

       -spooky n
               This option controls a kind of interesting effect  obtained  by
               using unnormalized normal vectors (how's that for an oxymoron?)
               in OpenGL.  A value of zero disables the effect.  Other  values
               vary  the lengths of the normals proportionally.  Okay, so it's
               not very spooky. Sue me.  Default: 0

       -complexity n
               Valid options are 1, 2, and 3. Everything else  is  treated  as
               though  it  were  2,  which  is  the default. This controls the
               number of polygons in the 'thing'. A value of  1  yields  1024,
               and the values go up in powers of 4. (i.e. 4096, 16384.)
                note:  There  is  an  inherent  lack  of  stability  at  lower
               complexity, which can cause the shape to devolve into a 'flying

       -speed n
               Controls  how  fast  the blob moves around the screen. Default:

       -spherism, -hold, -distance, -damping
               These options control the 'jigglyness'. The best way to explain
               these  is to explain how jigglypuff works. Basically, the shape
               is a tetrahedron whose faces are subdivided into  a  number  of
               triangles,  forming  a  mesh.  Each of the vertices of the mesh
               has two different forces applied to it: one proportional to its
               distance  from the surface of a sphere, and one proportional to
               the difference of the distance to each of its neighbors in  the
               mesh to a given ideal distance. In short, one tries to move the
               points into the configuration of a sphere, and the other  tries
               to  push  them  back  into a tetrahedron. The catch is that the
               points have inertia, so they always overshoot their target, and
               hence  they  oscillate.  The  magnitudes  of  the two forces is
               controlled by the options  'spherism'  and  ´hold';  'distance'
               specifies  the  distance  the  vertices seek to keep from their
               neighbors, with 500 corresponding to  the  size  of  the  start
               tetrahedron.   e.g.  if  you  were  to give the options '-tetra
               -spherism 0 -distance 500', you would  end  up  with  a  stable
               tetrahedron.  The  'damping'  option  can help to keep the blob
               from collapsing or flying apart. The option specifies the speed
               at  which damping starts, hence lower values mean more damping.
               Defaults: spherism: 75; hold: 800; distance: 100; damping: 500.

       -random Probably the only parameter you'l ever need.  Overrides  almost
               all  of  the parameters with random values. The values affected
               are: speed, spherism, hold, distance, damping,  spooky,  color,
               wireframe and tetra.  Default: off


       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 RESOURCE_MANAGER property.
