The DIY Player from Shao Wen is the coolest concept gadget that you are likely to see in some time. Imagine being able to have one device do everything you want without any compromises. That would be the DIY Player.
The DIY Player uses one static screen and a variety of interchangeable pieces to turn it into an MP3 player, cell phone, and camera. I love this idea. I can only wonder why something like this hasn't been made into a reality yet.
