We don't really have much use for radio over the airwaves -- hell, the closest we ever get to the halcyon days of rock'n'roll radio is the Flaming Groovies station on Pandora. But something as convenient (and as cute) as this next item just might get us back in the habit. A proof-of-concept by a small handful of designers (Wu Kun-chia, Wang Shih-ju, Chen Ming-daw & Liou Chang-ho), Flexio is a portable, printed, solar powered, paper-thin FM receiver that fits in a book -- or a pocketbook. Each radio is tuned to a specific frequency, so the design calls for boxed sets for different cities (for example, Taipei, Berlin, or Paris). Sure, it's probably not convenient to carry the whole box around with you, but you might want to hang onto KROQ in case you should ever find yourself wandering around LA late Sunday night/early Monday morning. Get a closer look after the break.
