I was in London last May doing some research (part of my dissertation) at Kew (Royal Botanic Gardens), and I also paid a visit to the British Museum of Natural History. The "Earth from Above" photos were all on display outside the museum, and were indeed quite striking, beautiful, and thought-provoking. Seeing the photos online is nice, but seeing all 100+ of them on display as very large prints (probably 1 x 1.5M or so), is really quite a memorable experience. I bought the book while I was there as well. I understand that they were still on display there as of early this year, so if you're interested, and can make the trip, I'm sure you'd enjoy them. I don't know whether they're still there though.
