Slightly nerdy pendants

Perhaps five years ago I was a big fan of the cartoon Avatar: the Last Airbender. It had an epic storyline, a complex mythology, and serious messages all combined with a delightful sense of play. It's one of those shows that you watch all the way through and then immediately want to start all over again. For some time now I've had this idea to make some pendants inspired by the emblems of the four nations on the show. This is what I came up with. They're somewhere between a quarter and a half-dollar in size, all made from polymer clay.
