What's better then a monster machine? A meta machine. Here are a bunch of machines that really took the advice "Just do you!" to heart.
A train that lays its own tracks
You can tell just how much this machine loves Fleetwood Mac by how it's Going Its Own Way.
Whatever floats your boat!
A crane that cranes itself
You can't always rely on others to build you up.
Trucks truckin' trucks
A 3D printer that (sorta) prints printers
It can only print the plastic parts, but that's a promising step toward a self-sustaining robo-apocalypse!
It's just plane impressive.
Every multi-stage rocket ever
Can you help a brotha out... of the atmosphere??!?!?!
