Of course I'm leading with the Turtles! It was either that or the Avengers. Over on Nerd Fashion's Esty page they have a huge selection of necklaces all similarly designed. I think they're actually kind of cool, though I'd be more inclined to attach them to something or hang them. You can check out the Avengers after the jump and the variety of nerd stuff on their site.
