In my opinion , we can use the same general idea ,but this time , "walking" / rotating around an axis for the purpose of our forum.
It's not the first time , when we must go back to nature...this time , in connection with the pendular "walking" of the celestial bodies (see Sun-Earth-Moon variable leverage model topic ).

For robotics , an inverted pendulum is the starting image (concept) , so maintain stability.
We can use the same starting point (image) to play unstability , also...and maybe , a continuous one , due to gravity fall and inertia .
