Japanese designer Jun Fujiwara's award-winning Re: Sound Bottle has a simple exterior that belies its complex interior. The software inside this bottle with a cork stopper is set in motion when the cork is removed. At that point, the device records any audible sound. The recorded sounds are then layered and arranged to form rhythmic tracks. Essentially, the user supplies the samples and the Re: Sound Bottle becomes the DJ.
