• Use the script of the play and make a comic book.
• Add additional scenes to the play that contain more logic puzzles.
• Locate and enjoy some books by Raymond Smullyan, such as This Book Needs No Title, What is the Name of This Book? or To Mock a Mockingbird. Not all of Raymond Smullyan's books are still in print, so you may have to hunt them down in a used book store or a library.
