Century of crosswords

On this day, the Solstice, exactly 100 years ago, Arthur Wynne designed a word-cross puzzle that was published in the New York World. It was the sudoku of its day and the idea was widely propagated until just about every newspaper in at least the English speaking world will include one somewhere in  its pages.  I've made up a few of these in my time, for events or for the hell of it.  The Easter egg hunts with which I tormented my children owe a lot to a lifetime to doing crosswords - my mother taught me the basic conventions of British-English cryptic clues before I reached double digits.
