Walking Octahedron

This could be a silly question but i have some rigs i would to test animate and play around with. Is there anyway i can render a rig, say using Octahedron display WITHOUT it being attached to a mesh? Thus, a walking rig in Octaheron display.

You could try this script, it may be useful:

i think ur saying u wann use a rig as ur mesh and trying to figure how to make it so bones get rendered?
