Animated elements?

[triplehelixxx]

I have a question. I've seen a few images on the Dev Diaries that would suggest some of the elements might be animated or have moving parts. Is this a thing? 

Landing gear for example look to have two states, deployed and retracted.

I've also seen, although cannot find, an image of an engine deconstruct into its various parts. Some of the parts look like they would spin or something, like the turbine blades.

Does anyone have any insight into this subject?

 

Much appreciated.
