Slow commute? No problem.
There's never a wasted moment when you have a smartphone, for better or for worse. Even underground users can patronize the "virtual supermarket," billboards that helps you make a shopping list later delivered to your door.
A group of students at the Miami Ad School envision putting that technology to decidedly more pleasurable use. "Underground Library," designed by Max Pilwat, Keri Tan and Ferdi Rodriguez, proposes a series of advertisements for the New York Public Library where a quick swipe could send the first ten pages of a book right to your phone.
