In the last fifty years, the construction of novelty forms (solid crossword arrays with unusual outlines) has almost died out. Three examples have appeared in previous issues of Word Ways: Palmer Peterson's Hollow Diamond (May 1971) and Armless Man (Feb 1980), and Walter Shedlofsky's Windmill (Aug 1973). (The latter occasionally appears in the Enigma, the monthly publication of the National Puzzler's League.) The two Linking Word Squares forms depicted below are believed to be new. Three is nothing exactly like them in puzzle literature; the closest analogues are the Cushion Square and the Hollow Diamond. Note that all squares are double, and that no words are repeated within a pattern.
