"Diagrams are meant to be clear and precise, serious and informative. David Greenslade shows them to be none of those. In his eyes they become murky and ambiguous, playful and misleading, harbouring deep, discomforting mysteries. Read at your peril: you will never be able to view a diagram in the same way again." - Donald Norman"Lyrical Diagrams is an exploration of how the imagination can be liberated by looking at language in a way that people hardly ever do. This work offers a remarkable, startling exploration of that potential. The unexpected lurks in the most innocent of diagrams. The items here are amusing, thought-provoking, intriguing-they illuminate in many directions, but perhaps none more than the extraordinary way that text and diagram demand new perspectives. This is one of those genuinely original books that continually astonishes." - Professor John Lee
