WHO MADE THAT? In true Maker spirit, the New York Times Magazine presents us The Innovations Issue, a delight for the eyes--and to navigate as well! The series explores the origins behind some of the most commonplace and quirky inventions that we take for granted from airbags to webpages and cat videos to ziplines. The authors came away surprised at "how few of the things we most value sprang from corporate labs or marketing labs...[but] came from people trying to solve a problem of their own." Strange and startling facts await. Did you know, for instance, that "this year average prom-going teenager racked up $1,139 in expenses?" Ridiculous.
