NAME
       jigglypuff - save your screen by	tormenting your	eyes.

SYNOPSIS
       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]

DESCRIPTION
       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.

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
	       visual.

       -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  sec-
	       onds.).

       -wireframe
	       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,	clown-
	       puke, chrome and	#xxxxxx	(i.e an	(old-style) X color specifica-
	       tion.) 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 num-
	       ber 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 complex-
	       ity, which can cause the	shape to devolve into a	 'flying  sno-
	       trag'.

       -speed n
	       Controls	 how  fast  the	blob moves around the screen. Default:
	       500.

       -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 con-
	       trolled by the options 'spherism' and 'hold'; 'distance'	speci-
	       fies  the  distance the vertices	seek to	keep from their	neigh-
	       bors, with 500 corresponding to the size	of the start  tetrahe-
	       dron.  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

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.
