Following the success of Letterform Variations, Nigel Cottier presents a study into the alphabet as medium in his new book Alphabetical Playground. From this has emerged a catalogue of numerous alphabets and letterforms (estimated at around 7,000 unique letterforms), all created using a series of systems, codes and themes to generate expression and form within the confines of the alphabetic code. With a theme or system for each letter of the alphabet, the book is an exploration into systems within systems, a code within a code.

Alphabetical Playground—an alphabetical system where each letterform can contain multiple letters within it, so a single piece of text can in fact contain multiple messages.
