Check out the clever Transforming music player from design genius Yong-Seong Kim. Like a mini-music system that couldn't figure out what it wanted to be when it grew up, this concept player readily transforms from a pocket MP3 player to a CD player with just a couple of clicks of the frame. Apparently, Kim had the idea while playing with a "dangerously cool" butterfly knife. And while the design is nothing short of brilliant, OhGizmo is stressing the fact that this is just a concept player. Like the concept cars at the auto show (the ones that run on jellybeans and create zero pollution), this will probably never make it to shelves. More at the always terrific OhGizmo.
