This is a terribly incorrect trivialization of the work they did. The idea is not to observe some meaningless pattern emerge. Instead, they're trying to describe the statistics of random 3x3 pixels taken from photographs of nature (in fact, only of the luminosity of each pixel, hence the black-and-white photos). At a first thought, you'd expect this to be completely random, but it looks like there is a certain statistical structure to it. You only find this structure far-fetched because you're reading a blogger's vulgarization of the scientific paper whose concepts you're not familiar with.

Unlike the unreasonable bible and Moby Dick codes, this has practical applications in image manipulation and compression.
