  The metrics of general relativity generally fall into two categories: Those
which are solutions of the Einstein equations for a given source
energy-momentum tensor, and the "reverse engineered" metrics -- metrics bespoke
for a certain purpose. Their energy-momentum tensors are then calculated by
inserting these into the Einstein equations. This latter approach has found
frequent use when confronted with creative input from fiction, wormholes and
warp drives being the most famous examples. In this paper, we shall again take
inspiration from fiction, and see what general relativity can tell us about the
possibility of a gravitationally induced tractor beam. We will base our
construction on warp drives and show how versatile this ansatz alone proves to
be. Not only can we easily find tractor beams (attracting objects);
repulsor/pressor beams are just as attainable, and a generalization to
"stressor" beams is seen to present itself quite naturally. We show that all of
these metrics would violate various energy conditions. This will provide an
opportunity to ruminate on the meaning of energy conditions as such, and what
we can learn about whether an arbitrarily advanced civilization might have
access to such beams.
