This set-up uses 3 spines. The spine is bound to the first spine which is stretchy and controlled via an IK spline. This is just a basic IK spine using clusters. I intend to put some limits on how far it can stretch and will also do a nice blendshape to give the mesh a nice look when it is stretched. This second spine serves to controll the back through FK. 3 FK controllers are hooked up to this 4 joint chain. The 3rd spine controlls the spines twist. I like this set-up because it gives the animator plenty of options. You have the direct controll of FK for easy posing, but lets say a tomatoe is flying at the character and you want to have the upper body shift slightly to the left. With Ik this is an easy task. http://www.griffinanimation.com/Storage/13.jpg
