You can display any object as a bone object. Select the object and then choose

Bone Tools from the Animation menu. This opens the Bone Tools floater. On

the Object Properties rollout, turn on Bone On. Then go to the Display panel,

and on the Link Display rollout turn on Display Links and Link Replaces

Object, which displays the bones instead of the object. This can be useful if

you have a geometrically intensive hierarchy to animate. The interactive

viewport response is faster when the geometry is hidden and displayed as links

only.

Any object hierarchy can be displayed as bones.
