I think the random shape of the rocks
is the complexity that Alasdair was referring to, so the cube, in fact, does
not have all the complexities of the randomly-shaped rocks.
Have you ever played the game "MouseTrap"? It's this ridiculously confusing contraption that drops a ball that taps a lever that makes a rubber band loosen and dump another ball, and other stuff like that, culminating in a little bell-shaped trap falling down onto the little mouse tokens.
This is a very bad and impractical design: it has way too many parts, and is, in fact, designed to fail at least occasionally, even when it's put together right, just to make the game more interesting. Some kids' marble tracks are the same way: designed to make the marbles bounce throuhg all kinds of weird obstacles before reaching the bottom. They're a pain in the butt to keep running.
Michael Behe's "irreducibly complex" mousetrap with the spring and hammer is a much better and more practical approach to mouse-catching, and it clearly shows the "intelligent" part of "intelligent design."
The human body (and the bodies of other organisms, too) actually show the first type of construction: a convoluted mess of genes that can be alternatively spliced, and all sorts of problems in the knees, the lower back, the hips, the feet, etc. that can happen to you even if you're taking good care of your body. There are people that make careers out of studying a single set of genes that controls how your entire bodyplan is laid out during embryonic development. One weird fluctuation in hormones, and the left side of your face doesn't form. Sometimes, for obscure reasons, the genes just don't do their job: for instance, the pinna of my left ear didn't develop properly, so I have one big Dumbo ear and one Evander Holifield half-ear.
The more parts you add, the more potential problems you create. Simplicity is intelligent, but complexity is nature.
Darwin loves you.
