The AIGA Journal of Design has an interesting article entitled Forever Skull, a look at the skull as a design icon.

As an icon, it will never die, not as long as we are flesh and bone. We might one day be cyborgs, but the skull as symbol will morph into something like a drive-in-theater speaker, a metallic encasement with antenna and a mesh mouth. From primate to hominid to homo sapiens to… robo skull. The skull will outlive us.

I sort of have to agree. The skull is one of the few constants across all civilizations and time periods. It’s interesting to see the various forms that it takes in art and iconography.
