Keith has written several long works of constrained writing, such as Cadaeic Cadenza, a story in which the number of letters in successive words spells out the first 3835 digits of the number pi; the book Not A Wake: A Dream Embodying π's Digits Fully for 10000 Decimals, which similarly encodes the first 10,000 digits of pi with texts composed in various literary styles; and the book The Anagrammed Bible: Proverbs, Ecclesiastes, Song of Solomon, co-written with Richard Brodie, in which the roughly 95,000 letters of the original text are rearranged into a modern paraphrase.
