Public Radio International has released its first book for the iPad, the Studio 360 Teacher Redesign multi-touch book, available free via the iBookstore. For the last five years, PRI’s culture show Studio 360 with Kurt Andersen, produced at WNYC, has hired graphic design teams to rethink the images of things as diverse as Uncle Sam, the gay-pride flag, the Monopoly board game and Valentine’s Day. Last fall teacher Kate Ahearn of Haverhill, Mass., suggested a revamp of the image of teachers. Studio 360 recruited New York design firm Hyperakt, which created new campaigns to recruit teachers, designed new bathroom signage — even temporary tattoos. The creative process and those visuals are documented in the interactive iPad book. The book and more information on the project is also available at its site, InspireTeachers.org.
