Here's the abstract to the paper, it's Complexity Science
in action, an engineering dept looking at biological systems.
Darwin in abstract form so...any department can put nature
into their field.
The fractal designs they generated aren't new at all, only they're
generating them with chemical reactions instead of with a
computer printout. Bringing the fractal designs to life
so to speak.
I bet before long, the local Target Garden 'Dept' will have
shelves full of such natural designs, and as intricately
and finely detailed as can be imagined.

By studying natural shapes and processes, researchers have learned that the
key ingredient to arriving at complexity is the coupling between different
processes. This coupling leads to self-organization and is an essential
feature of life (1). In biominerals, such as diatom skeletons or abalone
shells, the interplay between calcium carbonate or similar minerals with
organic molecules can lead to highly functional materials with hierarchical
architectures and stunning beauty (2). On page 832 of this issue, Noorduin
et al. (3) bring the man-made design of complex shapes from simple
ingredients to a level of control that promises applications in fields such
as optics and catalysis.

If anyone finds designing nearly perfect replicas of natural systems
interesting, they might find the math of L-systems fun.
You can see how a very simple set of deterministic equations
or a very simple relationships, iterated into itself, can
build such beautiful and complicated forms. The mathematical
representation of cell division.
A simple set of computer instructions like this below
can generate an biologically accurate representation
of various plants.
L-System Plants Tutorial
Weed {
Angle 50
Axiom +++++++++++++x
x=f[@.5+++++++++x]-f[@.4-----------!x]@.6x
}
"The replacement string for the weed x says draw a line (f), the stem of the
weed. Next, shrink the weed by .5, turn left 9*7.2=64.8 degrees, draw the
shrunken weed, and return to the stem ([@.5+++++++++x]). This draws the
lowest branch of the weed. Next, turn right slightly (7.2 degrees) and draw
another portion of the stem (-f). Continuing, shrink the weed by .4, turn
right 11*7.2=79.2 degrees, reverse the meaning of right and left, draw the
shrunken weed, and return to the stem ([@.4-----------!x]). Finally, draw
the weed at .6 size (@.6x).
Here is how the Weed L-system looks."

I think the terms natural and man-made should be defined more
clearly first. Natural is a process where the final product is
allowed to emerge as it will. While man-made would be
where the final product is defined in advance, with the parts
and conditions manipulated accordingly.
If you can predict the future, it's not the product of an evolving
or natural system. And there lies the Great Contradiction
between objective certainty and understanding nature.
So are those 'beautiful flowers' created by the researchers
man made or natural? If the reactions are tweaked along
the way for a desired outcome it's man-made, if the
initial instructions are left alone play out as they will, then
it's natural.

Besides, a truly intelligent design should be when the systems
design themselves. Where the only 'intelligent' involvement
is setting the initial conditions or instructions, and it takes care
of itself from that point on.
Self-Organizing Systems (SOS) FAQ
Frequently Asked Questions
Definition of Self-Organization
"The essence of self-organization is that system structure often appears
without explicit pressure or involvement from outside the system. In other
words, the constraints on form (i.e. organization) of interest to us are
internal to the system, resulting from the interactions among the components
and usually independent of the physical nature of those components. The
organization can evolve in either time or space, maintain a stable form or
show transient phenomena. General resource flows within self-organized
systems are expected (dissipation), although not critical to the concept
itself.
