  We look at an electric charge in hyperbolic motion, and we describe some
arcane geometrical aspects of the electrodynamic interaction. We discuss the
advantages of a time symmetric formulation in which the material point
particles are replaced by infinitesimal length elements along their worldlines.
We show that the four-force obtained from our geometrical model is very closely
related to the "electrostatic" four-force obtained from Fokker's time symmetric
action.
