  In this paper we study some features of the Kerr metric both from an analytic
and a visual point of view by performing accurate raytracing in various
situations. We focus on features that are unique to the maximal analytic
extension of the Kerr metric as compared to that of the Schwarzschild or even
the Reissner-Nordstr\"om one. A large number of new, yet underexplored
phenomena appear, especially regarding the structure of bounded null geodesics
and the aspect of the negative gravity regions whose visual characteristics are
shown both from outside and inside it.
