I can't really think of any other fanfic-related ones (though there is that one I just sent that mentions mine but in a broader context). I decided not to finish off that survey because I don't have time to read all the ones mentioned and no one seemed to agree much.
However, if the mood strikes me, I'll try to draw some sketches for that theme park article I did so poor Prawnie can have something visual. Otherwise, I'm kinda stuck for article ideas (and school has been in the way lately).
