There are tons of cool LEGO CNC machines that have been made. The one pictured above can be seen in operation here (unfortunately we can’t embed the video here). It shows how so many people have real creativity since these CNC machines are obviously only for fun since a LEGO frame would not be adequate for doing any real work. Nice thing about LEGO is that once your design is done you can rip it apart can move on to your next creation. I am still waiting to see a LEGO pick and place machine populating surface mount components onto a circuit board.
