Lego Machine Sorts Lego

You should be familiar with The Great Ball Contraption (if not then watch it first), but this is a new example of engineering taken to the next level.  This beautiful machine sorts Lego axles into their appropriate containers based on size.  The elegance and genius of the design is incredible.

All ten different lengths of axle are sorted into each bin to be packed away, the design of the sorting mechanism is imaginative to the extreme.  It simply lets the axle drop into the right bin if it is greater than twice the length of the supporting brick underneath, the size of this brick decreases until all the axles are sorted, simple yet very reliable.  Even if you’re not a Lego fan, you must admit that this is really cool.
