Scott and Francois - Yes - shots like this do make one a believer in the fractal geometry of natural phenomena.
Nancy - I was indeed being a bit sloppy with my language, but I thought that 'too two-D' didn't really communicate my question about flatness. After all photographers go to great pains to convince everyone that we indeed don't live in flatland. Anyway, if the language that I commonly hear in the media is to be taken into account, I should have said 'too too two-D'.
I hope you have a binocular microscope!
