It may not be quite capable enough to let you build your own Weighted Companion Cube, but those looking to try their hand at a DIY CNC milling machine won't likely find many more straightforward options than the MTM Snap. Built by Jonathan Ward of MIT's Center for Bits and Atoms, the machine itself is constructed from some high-density polyethylene parts milled on a ShopBot (which simply snap together as the name suggests), and it's controlled by an Arduino board that lets you operate it from any Mac, Windows or Linux computer.
