There's a bit of creative licensing in the meta answer. And the mechanism requires a bit of out of the box thinking.
Anyway, to my surprise one of the hardest parts of constructing a crossword is making a grid pattern that feels natural and works. This entire puzzle was an experiment. I "borrowed" another grid pattern and entered the themers and let the Crosshare software do all the rest of the work. I'm not sure what I learned. It had to have been something though. Otherwise there would have been no point in doing it.
