I stumbled on this while wandering through Restoration Hardware yesterday. The Firefly Visual Dictionary ($33.97 at Amazon) is chock full of infographics breaking down, for example, all the parts in a power transformer pole outside your home. Or the innards of a windmill. You name it, it’s in here. Close to 1,000 pages with over 6,000 illustrations, this is the kind of book I loved to read all the time as a kid. I’m going to have to pick this up sometime soon.
