Architect Karen O'Leary creates fully realized cities every day without a single brick or beam. Her cities can be seen in hotels, retail stores, restaurants, and books -- and on her online store, StudioKMO, naturally. How? Karen's cities and towns are actually mind-blowing, meticulous, hand-cut paper maps and ink drawings. In her own words, a map is "more than just a navigational tool, it also tells a story." In this week's Playlist, Karen provides a little bit of her story. Take a listen.
