Korean gadgets these days are either gunning for next-to-nothing thinness or mind-boggling transparency, which is marvelous. Today we came across another Korean company (and an old friend), Fils, which does transparent "sound film" speakers in many forms: photo frame, umbrella, curtains, cap, hoodie and even model yacht (yeah, seriously), all thanks to the highly-flexible piezoelectric film. Sure, the sound quality was hardly top-notch, but apparently Fils is hooking up with a few big-name Korean electronic companies (TVs?), so we're all going to suffer soon whether you like it or not. Cheer yourself up with the video after the break.
