Really nice, however I there is some buggy behavior in this logic simulation: It can end up in an inconsistent state: I have a little Robot Odyssey experience where it would loop forever between inconsistent states. However that design is not perfect either, it's still much better than this in my opinion. The interface is quite nice though.
