Available here. Why did I do it all in raw Postscript (for the grid) and a lot of LaTeX picture commands (also for the grid)? Because I can. And also, now that I've done it once, I can automate for the future (should the future hold more of these).
UPDATE (8/11): Updated and fixed version here! The automated tools appear to work fine; I just have to come up with a typesetting style I like. (Four-column is standard, because it's the only way to go; it's dealing with the long clues/answers in a reasonably sane way that is eluding me so far -- and I can't seem to get \raggedright to work for whatever reason.)
