Physic based libra (scales)

Hi guys! i’ve been thinking if it is possible to create physic based libra (scales), like the one in “TRINE” (http://www.youtube.com/watch?v=1_umCT61fSQ&feature=related 7:46) in Unity.
If anybody have some ideas please share :stuck_out_tongue: .
Thnx!

This can be done using hinge joints. They’re very simple to use - it’s just a matter of adding the joint component to the object and then choosing the position and rotation axis of the hinge.
