How would you like to have a rig that you could manipulate to your heart's desire? Something with limbs that react like an accordion. In production, I believe, they call this ribbon spline control. It allows an animator to control a rig and make it bend to his wishes--almost as easy as drawing out the pose. BIT, the bending and stretching robot rig, can do this. It is fitted with with ribbon splines on each limb, body and neck (practically everywhere) allowing his accordion-like limbs to stretch and bend to your wishes.
Only downside is shin and arm guards. It's a bit of a design flaw, cuz the appendage does not allow for a wide range of movement. But I rectified it with an extra controller (that occasionally has a mind of its own) that you could use.
