A Lego printer made of Lego that prints Lego models, we must go deeper!
Behold the Lego Mindstorms NXT 3D Lego Printer, it can print 3D Lego models using standard Lego bricks.
The robot uses 3 Mindstorm NXT robot brick’s and 9 motors. You can find more information and build instructions at http://www.battlebricks.com/makerlegobot
They don’t need us anymore, they will self-replicate until the entire world looks like an 8-bit videogame!!! And then humanity will die impaled by Lego bricks, starting with our feet, because they seem to be magnets for these plastic a-holes.
