While doing research for prior posts about web shops that "sell" Cyborg equipment and augments I found this site quite interesting.
Shannon Larratt from BMEzine.com wrote a very interesting article on how piercing can be more then just decorative art. It can actually serve a purpose, just like pierced tongue (go for it ladies).
I also wear an eye piece so this approach to the classic "problem" of that is the best way we can augment our eyesite is interesting to me.
One distinct problem with this approach is that to many people still distrust or are disgusted by a thought of inserting a foreign object into their body.
But this is a completely different debate.
