Maker Bot is awesome because it's a 3D printer that's also open source and plays Daft Punk tunes while it's at work. And it's meant to be hacked, so this item is limited only by your imagination.
The formal name for this MakerBot is the Cupcake CNC, and is able to rapidly prototype anything. It consists of a series of belts and pulleys, laser cutter, a wood cabinet and a stepper motor. And really, it's hard to complain about anything that plays "Television Rules the Nation" as a pure aside.
