In this speculative, millenial essay, I try to anticipate what sort of novelgravitational optics investigations might be observed, after it becomespossible to map and monitor roughly a trillion sources (of which a billion maybe usefully variable) comprehensively throughout electromagnetic and otherspectra over the whole sky. Existing techniques suffice to produce threedimensional maps of the dark matter distribution of the accessible universe, toexplore black hole spacetimes and to magnify images of the first luminoussources, terrestrial planets and compact objects.Comment: 4 pages PASP Millenium Essay in pres
