Graphic for documentation title page

[Rik]

5/10/10

All,

The title page of the documentation is rather sparse with a title bar near
the top, authors near the bottom, and a large white hole in the middle.  I
thought it might be nice to show off what Octave can do by putting a fancy
graphic in the middle of the page.  Is there any particular plot which
developers think best represents Octave?

Perhaps sombrero?  I checked the website
(http://www.gnu.org/software/octave/index.html) and the title graphic there
is either a sombrero plotted with contourf or a Lorenz attractor.
