Query: A classical fermionic system that follows the fundamental rules of
  Quantum Mechanics   It is feasible to obtain any basic rule of the already known Quantum
Mechanics applying the Hamilton-Jacobi formalism to an interacting system of 2
fermionic degrees of freedom. The interaction between those fermionic variables
unveils also a primitive spin and zitterbewegung.
