Hi again,

Here is a first draft : http://addictedtor.free.fr/misc/wiki.png
I would like to put some code on the left, but i'm not inspired which 
code, something simple, involving iris maybe, i don't know.
Maybe something with a puzzle or a planet, or both (echoing the symbol 
of wikipedia) ...

Any ideas

Romain.

I started that hacking demo(bivar) from rgl  :

 require(MASS);

  # parameters:
  n<-50; ngrid<-40

  # generate samples:
  set.seed(31415)
  x<-rnorm(n); y<-rnorm(n)

  # estimate non-parameteric density surface via kernel smoothing
  denobj<-kde2d(x, y, n=ngrid)
  den.z <-denobj$z

  # generate parametric density surface of a bivariate normal distribution
  xgrid <- denobj$x
  ygrid <- denobj$y
  bi.z <- dnorm(xgrid)%*%t(dnorm(ygrid))

  # visualize:
  zscale<-20

  # clear scene:
  clear3d()
  clear3d(type="bbox")
  clear3d(type="lights")

  # setup env:
  bg3d(color="white")
  light3d()

 
 
  # Draws parametric density
  surface3d(xgrid,ygrid,bi.z*zscale,color="yellow",front="lines", 
back="cull")

 # the file is from here : http://developer.r-project.org/Logo/
 rgl.bg(sphere=TRUE, texture="/home/romain/Rlogo-4.png", back="filled" )
