Benzene is modeled using
rotating/precessing discs for
placement of the electrons:

This is a 72 frame loop.
30 electrons are each traded to a
neighbour atom and back continually.
All discs are always parallel.
Neighboring discs have opposite
rotation.
Each disc rotates 10 degrees and
precesses 20 degrees every frame.
Voila.
