I will describe a new numerical effort to solve Einstein gravity in
5-dimensional asymptotically Anti de Sitter spacetimes. The motivation
is the gauge/gravity duality of string theory, with eventual application
to scenarios (for example heavy ion collisions) that on the gravity side
are described by dynamical, strong-field solutions. As a first step
towards modeling such phenomena, we initially focus on spacetimes with
SO(3) symmetry in the bulk; i.e., axisymmetric gravity, dual to plasma
dynamics on the boundary with spherical or special conformal symmetry.
As a test application we explore quasi-normal ringdown of highly
deformed black holes in the bulk, and examine the degree to which the
expectation value of the dual boundary stress tensor agrees with that of
a conformal fluid.
