Looks like a ball and socket mechanism to me.  Easier to fabricate would be
link-and-pin.  The metal parts are tubes (possibly as suggested above).  Between
tubes would be plastic rods (smaller diameter than tube).  Rods attach to tube
by pins.

Got to watch edges though (corona discharge).

I don't think that the balls on string idea is so impractical - you just need a
V-belt pulley at either end.  (Diameter of sphere slighly less than normal width
of V-belt.)
