The Lorentz group acts on the projectivized light cone in the three dimensional Lorentz space as the group G of M�bius transformations of the circle. We find the closure of G in the space of all measurable functions of the circle into itself, obtaining a compactification of it as an open dense subset of the three-sphere, with a dynamical meaning related to generalized flows.
