Here's a novel idea. Take a used camera lens, reshape it, polish it and voila, a beautiful piece of wearable geeky jewelry.
Camera expert Craig Arnold has created a line of bracelets entitled "Re:vision," which come in eight different models with different names pertaining to each.
This white one, entitled the focus cuff, is one of my faves, but they are all so unique it's hard to pick just one! Prices range from $175 - $250 for the bracelets, so I don't think I'll be getting one anytime soon. But still, such a neat concept for a bracelet!
