This is a set of Vnyan nodes that when triggered, cause the model to spin for a short time, then stop and reset the rotation to 0.
You may want to adjust which model bone the rotation happens from by changing the Game Object Name fields on the two Object Rotation nodes. A hip bone may be a good choice!
Originally tested on VNyan 1.6
