Was looking to do this http://www.motionscript.com/design-guide/elastic.html

but where the layers are 3d. 

Has anyone adapted this and got it to work? I've been trying but failing. 

My leader layer is moving xy and z and also rotating in xy and z. I need another layer to be above it (in z) and connected but springy/elastic-y.

Thanks for any ideas!
