Fancy vs. reality...

         Hi Jim !
Keeping  the old,classic point of view about a possible (impossible?!) gravity powered device,we must play gravity fall and inertia...so mechanics,only.
If we add the magnetic play ..it's interesting,but the "skeleton" design,must be firstly..."pure" mechanics.
My suggestion::try to play a "modified" trebuchet (in the top position.it can "throw"the short arm into a long arm...)
       All the best! / Alex

.....we can start  with a fancy,an illusion of continuous  motion due to gravity,inertia ...and a "hidden" electric battery ,at :

  but this decorative object,can it be easy modified into a practical self-moving one ,due to gravity  fall and rotationalinertia,only !?
