Lego technology

I was amazed by the engineering wittiness of the Lego photocopier. But I'm double dazzled by the Lego 3D printer.

Not only does it enable you to cast things in any shape you want, "printing" any shape you send to its software like in normal 3D printing, which is cool enough right there --- not only does it do this in a machine made from Legos, which is that much cooler --- but it casts its printout in chocolate, which may well make it the coolest machine ever.
