Students of wordplay have long recognized a cornucopia of variant word-set arrangements. Pyramids, half-squares and diamonds have been themes in Word Ways from early issues on. Windmills, hollow diamonds, and hollow-cross forms are among other forms examined in this magazine's pages. My own past forays have tracked such shapes as hollow squares, compass roses, and word lattices.
