ABSTRACT
As we have seen in the last chapter, it’s a crazy world out there, with all manner of strange goings-on: dissections swinging with wild abandon, swingers transforming into twisters, whole families twisted beyond recognition, and puzzles that that defy our best efforts at solution. We could even have seen a “hex-change operation” (such as an exotic twisted dissection of a triangle to a hexagon), but the author thought it better to hush up those things.
