After flicking through a copy in a bookshop whilst on holiday, I recently got myself a copy of The Magic of Reality. I've not read through much of it yet but I've enjoyed the first few chapters (despite not really being the target audience). The thing I have loved most, though, has been the visual impact. Every page is stunningly illustrated and not just in a "here's a few nice relevant photos" kind of way; instead, the text and illustrations weave around each other with a greater-than-the-sum-of-the-parts impact.
Of course, Dawkins has Dave McKean to thank for the amazing illustrations but it is hard to believe that the images and text could work so well together if he has not also had some input.
I've also found out that you can get it for the iPad for £9.99. Even though I have the book, I must admit that I am sorely tempted.
