I have to agree with previous commenters. This is an excellent little setting full of wonderful ideas put together with great care into a coherent whole. It's weird in the best sense of the word.
But I also have to agree that this entry probably doesn't conform with the four A5 pages limit. The paper size in the PDF seems to be letter size and the text is already quite small. I believe it would be borderline unreadable on A5 paper. Which is a shame, really, because I think this module deserves a high rank in the final results.
