Making a cube in a cube in a cube from one block of metal is impressive

sploid.gizmodo.com: There is probably some negotiation with the Earth’s magnetic poles or some sort of magic going on here because somehow this guy is able to make a cube inside a cube inside a cube from a metal block. I have no idea what’s going on in the video half the time but watching the block get shaved to house three independent cubes within each other is pretty damn crazy.
