Following the success of Letterform Variations, Nigel Cottier presents a study of the alphabet as a medium in his new book Alphabetical Playground. The result is a catalog of numerous alphabets and letterforms (estimated at 7,000), all created using a range of systems, codes and subject matter to generate expression and form. The themes range from A: Alphanumeric: a family of alphabets all structured according to the alphanumeric code (A = 1, B = 2, C = 3, etc.), above C: Cursive: An allusion to cursive writing systems and sequenced alphabets consisting of letters formed with a single continuous line, to L: Letterswithin Letters: An alphabetic system in which each letterform can contain multiple letters, so that a single text can actually contain different messages.
