It is also worth mentioning that Lego makes a great mechanical prototyping medium. A big advantage is being able to quickly iterate and demonstrate something that works in the real world. In simulation, it's easy to forget about things like friction*, deformation, slop, backlash that aren't simulated. That being said, it is high time that someone made a mechanical construction set simulator for VR...
