Where do LEGO bricks come from? Why, from the LEGO factory, of course. And in a bit of LEGO-ception, here’s a LEGO factory built of LEGO by BrickJonas. This model looks as if it just came off a designer’s drawing table in Billund, complete with a full interior, removable roofs and modularity. I wonder if this factory produces bricks to build a LEGO factory?
