We consider discrete congruences of touching spheres in Lorentz space and show how they correspond to circle patterns. Our correspondence is a sphere geometric interpretation of a Lorentz lift previously introduced by Chelkak. Moreover, we identify a special case of circle patterns that corresponds to S-isothermic surfaces in Lorentz space. Finally, we discuss a case that is even more special: the case of maximal surfaces in Lorentz space. This talk is based on joint work with Dellinger, Müller, Polly and Smeenk.
