Simplicity is often an intricate situation concealed in a broad appearance, by subsumption of the many under the one (or the few). A pale blue dot suspended in a darkish background, for instance, may seem pretty uncomplicated and elementary -- and thus a potential candidate for a select person's idea of beauty. But at a different scale or POV, where more details emerge from the generalization of either that initial image or its concept, some areas of its internal complexity can get pretty ugly. Since no stipulation was made about such having to be universal and independent of personal judgment, then this would apparently be a case or example of it being so.
I just thought I'd add that simplicity is relative to the nature and function of the system in question (see BillyT's response on the first page). For instance, what defines beauty is the simplicity of a human being's appearance according to his comparison to other human beings or what he/she looks like relative to others based on evolution and other factors.
