MakerLegoBot is made of Lego, makes things out of Lego, is so meta it hurts (video)

Building things out of Lego? Lots of fun. Building a thing out of Lego that itself builds other things out of Lego? That's totally mindblowing, and that's what Mindstorm master Will Gorman managed here with his MakerLegoBot masterpiece. The machine takes input from a PC running MLCAD, a sort of industrial design tool for blocknauts, and then churns out anything you like -- so long as it is comprised of 1x2, 2x2, 3x2, 4x2, and 8x2 bricks. These are fed by the machine and methodically placed in exact position, as shown in the video below. If you're hanging out in The Netherlands this upcoming weekend you can also see the thing in action at LegoWorld in Zwolle, or just build your own with the detailed plans at the source link below. But, before you start assembling, know that you'll need 2,400 bricks and nine Mindstorms NXT motors.
