Revisiting The 99% Invisible City

In this episode of 99% Invisible, Roman Mars and Kurt Kohlstedt revisit a special episode created to launch their book, "The 99% Invisible City," five years prior. They explore the design stories behind everyday objects found right outside their Oakland headquarters, such as anchor plates, fire escapes, planters with defensive design, utility markings, speed bumps, traffic lights, manhole covers, microwave relay towers, road markings, and sidewalk plaques indicating private property. The episode also includes a discussion about the process of creating the book, including gathering material, organizing topics, and the differences between audio storytelling and writing for a book.
