Looking at this one, I get the impression that perhaps we aren't seeing its best side. It's always hard to get a sense for what's in front and what's in back but this one is especially difficult. At first it seems random and asymmetrical but running vertically through the image is a curve which looks a lot like a graph of the cube of x.

The outer portions are a tad grainy and blurry because they are WF data while the inner section came from the PC chip so it's nice and smooth.
