Your job, should you choose to accept it, is to comment on this thread explaining the most awesome thing you've done this since July 1st. You may be as blatantly proud of yourself as you feel. You may unabashedly consider yourself the coolest freaking person ever because of that awesome thing you're dying to tell everyone about. This is the place to do just that.
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do". Not "are working on". Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods.
So, what's the coolest thing you've done this month?
This seems like it would work a lot better as a computer program, where the crossword cube can be rotated by the user to see the different fields. Otherwise a 7 x 7 x 7 seems like it would be too large for a newspaper, where real estate is limited (not to mention the difficulty in doing the "depth" part of the crossword). Making it virtual (either a standalone app, web app, steam game) solves most of the potential problems.
Well, here is a low-tech version of a user interface. Printed (3D) crossword. Or at least printable. Perhaps it would do for some.

The virtual spaces could be also somewhat filled with them, yes.
