Here you can see my variableFK node beeing used to animate a tentacle in maya.
The deformation is done with a FEM-simulation in Houdini.
And a Tension/Compression Attribute in Houdini to drive smooth/wrinkle skin deformation.

This is a rig I made when I first learnt rigging.

Dinosaur rig

This rig was made to learn about diffrent deformers and correctives.
