Chandra X-ray imaging has shown that equatorial tori, often with polar
jets, are very common in young pulsar wind nebulae (PWNe). We review how
simple models of these toroidal structures can provide
(nearly) model-independent measurements of the neutron star spin
orientation. Abetted by recent progress in measuring pulsar proper motions
and ininterpreting polarization observations, the PWN images give a set of young
pulsars for which we can compare the linear and spin angular momentum
vectors. If preserved since core collapse, these vectors give an important
new handle on kick dynamics and, less directly, core collapse
physics. Early modeling of the data set shows significant constraint on the
pulsar initial spin and kick amplitude and timescale. We comment briefly on
other kick constraints and onthe connection with core modeling.
