We define branched bending deformations as deformations supported on a piecewise totally geodesic complex of (n-1)-dimensional faces meeting along (n-2)-dimensional branching loci. We establish a lower bound on the dimension of the deformation space of such manifolds containing a branched complex, and establish some facts about the Borromean rings as a special example (recovering a result of Menasco and Reid). With time permitting, we'll discuss some future directions.
