The 128-page hardback contains a series of his "odd yet perfectly logical" drawings of inventions – demonstrated in a new set of animated gifs – and is a follow-up to an earlier paperback version.

"Dominic Wilcox's drawings aren't just witty and beautifully drawn, they are serious challenges to the real world to keep looking at itself with innocent eyes, wondering what else is possible," said designer Thomas Heatherwick.
