The boring machine is rather interesting. It will dig tunnels in the direction it is facing for as long as you like. With the GUI, you can control the tunnel shape, and, if the cobblestone and dirt spewing out of the machine bothers you, disable the item drops. Harder materials require more power and torque to dig -64W per hardness points of the blocks in front of it, and up to 512 Nm of torque to cut through the harder materials. The borer will ensure that the tunnel roof does not collapse by replacing sand and gravel. Rumor has it that certain underground mazes found in a mythical forest are easily conquered with this machine.
