Stewart Coffin has been called "the most outstanding designer and maker of interlocking puzzles that the world has ever seen". He is credited with over four hundred designs spanning a huge variety of genres, including striking polyhedral sculptures, ingenious tray-packing challenges, and pioneering examples of interlocking cube puzzles. He has also written extensively on puzzle design and craftsmanship, most notably in his books Geometric Puzzle Design and AP-ART: A Compendium of Geometric Puzzles (see link to the latter below).
