I first started following Rick Smolan's books about 6 years ago (they only produce one every few years or so), and these photo books remain some of the only non e-books I would consider buying anymore... Always beautiful, and often thought-provoking. As a software engineer, this last one on Big Data hits pretty close to home, and I wasn't sure I'd have the same reaction, but I was quite impressed. If you're not convinced, there's a free preview of the book here (mid-way down the page)...

The info graphics alone are way too cool. Just my 2-cents...
