Conundrum is a mind-stretch. Encrypting idioms into their typographic equivalents, Harry enlivens our everyday language and challenges readers to see that "time after time after time" or, at least, "more often than not" "the writing is on the wall." For fans of word puzzles, sudoku, crosswords, and all manner of mind games, Conundrum offers an artfully packaged, cleverly designed new challenge. Drawing upon, literally in this case, graphic puzzles that he began creating as a child, Harry's developed over 100 witty conundrums for this book that will stretch the mind as well as delight the senses. A member of the Alliance Graphique Internationale, a frequent lecturer and contributor to design discourse, an internationally recognized leader in design, and a founder of Lippa Pearce, one of the UK's most respected design agencies, Harry refines the way we see and communicate. Conundrum achieves nothing less than changing how we understand and interact with language.
