I don't have any, but my cousin has the Hylian shield from the Legend of Zelda tattooed on his arm. It's pretty sweet. I wouldn't want that, per se, but I wouldn't mind having just the triforce. Not that I ever will.
My dad has the phrase "Let Go" in Elvish (from Tolkien) along with a dove tattooed on his arm, in reference to his wife and my mother who left him for no reason and broke his heart.
