This talk is about fiber bundles whose concrete fibers are each equipped with a Riemannian metric whose sectional curvatures are constrained to lie in a fixed interval I of real numbers. Prominent among these will be I=(-infinity,0), [0,+infinity) and (1/4,1]. This is a report on joint work with several people including Pedro Ontaneda, Andrey Gogolev, Igor Belegradek, Vitali Kapovitch, Zhou Gang and Dan Knopf.
