“In 1953, while working a hotel switchboard, a college graduate named Shea Zellweger began a journey of wonder and obsession that would eventually lead to the invention of a radically new notation for logic. From a basement in Ohio, guided literally by his dreams and his innate love of pattern, Zellweger developed an extraordinary visual system — called the ‘Logic Alphabet’ — in which a group of specially designed letter-shapes can be manipulated like puzzles to reveal the geometrical patterns underpinning logic.” (Thanks Design Observer!)
