If you're one that enjoys modding strange objects into even stranger gadgets, then you'll love the new MOTZ DIY Music Box.
The little MP3 player consists of only the absolute basics needed. All you have to do is find something cool to put it in. You'll get a USB 2.0 connector, and 256MB of storage, which isn't much but it's still a cool idea.
One of these will set you back about $40, that is if you can get one shipped from Korea.
