Too hot to do anything? Bored at work? How about brushing up on your skyscraper history by checking out the History of Heights presentation of the Skyscraper Museum? History of Heights is a 36-foot long mural which is part of the permanent exhibition of the museum, but for those of you who are not living near downtown Manhattan it also comes as an interactive presentation of the 162 flash cards of towers, skyscrapers, events and moments in skyscraper history. Each card tells you why the subject matters and is illustrated with historical prints and photographs. A fun fact guarantee!
