The geometry of Nadirashvili's complete, bounded, negative curvature surface I would like to understand the geometric structure of
a surface that Nadirashvili constructed which resolved what
was known as Hadamard's Conjecture.
Perhaps in the 15 years since his construction, others have
redescribed the example, and perhaps even made a graphics image of it?
Background.
Hilbert's theorem that implies that the hyperbolic plane cannot
be realized as a surfaces in $\mathbb{R}^3$ is well known.
Perhaps less well known is Hadamard's Conjecture, which
asked if there is a complete negative curvature surface
in a bounded region of $\mathbb{R}^3$.
This is discussed at some length in Burago and Zallgaller's
book Geometry III: Theory of Surfaces.  The problem was
solved after that 1989 book was written, as Berger explains
in A Panoramic View of Riemannian Geometry (p.135):

(Incidentally, the answer to this related MO question on Compact Surfaces of Negative Curvature
does not resolve my question, as it relies on Burago and Zallgaller.)
Here is the citation:

Nikolaj Nadirashvili,
  "Hadamard's and Calabi-Yau's conjectures on
  negatively curved and minimal surfaces."
  Invent. Math. 126(3) (1996), 457–465.

The main theorem is this:

Theorem. There exists a complete surface of negative Gaussian curvature
  minimally immersed in $\mathbb{R}^3$ which is a subset of the unit ball.

I have studied the paper, but my grasp of the underlying
mathematics is not strong enough to convert his description
into a geometric picture.
If anyone knows of later discussions that might help, I would
appreciate pointers or references.  Thanks!
Edit. I was not able to access MathReviews until now. This is from the review by M. Cai (MR1419004 (98d:53014)):

For the proof, the author starts with a minimal immersion of the unit disk into a fixed ball in $\mathbb{R}^3$ with the Gaussian curvature of the immersed surface being negative, then he inductively defines a sequence of minimal immersions of negative curvature into the fixed ball in such a way that the sequence converges to a complete immersion.

This helps.
 A: The conjecture attributed to Hadamard, if one regards that as being concerned with the existence of a complete embedded negatively curved surface in a ball, is still open. I have read the corresponding papers of Hadamard, and I think that it is fairly clear that he was concerned mainly with embedded surfaces.
The book Geometry III, edited by Burago and Zalgaller, contains articles by Rozendorn where the Hadamard conjecture for embedded negatively curved surfaces is discussed. It is also proposed there what the surface should look like: a coral with a fractal structure, as shown below. 
                                     
The basic idea here is that the surface (or the coral) trifurcates at a sufficiently rapid rate as it approaches the boundary of the sphere, thus each point of the surface will be infinitely far from the boundary of the ball as measured within the surface. The tricky thing here, which has not been verified, is that these pieces can be glued together without the creation of flat points. It is known that the individual constituent pieces can be negatively curved.
A: In fact the conjecture becomes true if you add embedded to the
hypothesis according to a theorem of Colding and Minicozzi.
(Colding, Tobias H.; Minicozzi, William P., II The Calabi-Yau conjectures for embedded surfaces. Ann. of Math. (2) 167 (2008), no. 1, 211–243.)
Who knows what Hadamard actually had in mind.
(Sorry this should have been a comment, its certainly not an answer to the
question.)
