I decided to try the UK calculator, for literary works. I'm somewhat horrified by the fact that one of the questions is 'Is the work "Peter Pan" by Sir James Matthew Barrie or an adaptation of that work?'<p>When specific works and specific authors have special laws passed for them, there's something a bit wrong with your legal system.<p>(And yes, I knew about this exception already, but wasn't thinking about it going in so the question caught me by surprise)
