  The high resolution capabilities of the High Energy Stereoscopic System
(HESS) introduced a new era in Gamma-Ray Astronomy, and opens a new window on
pulsar wind nebula (PWN) research. A rotationally induced jet (associated with
PSR B1509-58) is resolved for the first time in gamma-rays, allowing us to
trace the particle transport directly, without having the complicating effect
of spatially varying field distributions on the synchrotron emissivity. For PWN
older or more extended than Crab (i.e. those with lower field strengths), HESS
also reveals the properties of electrons contributing to the EUV/soft X-ray
synchrotron bands, whereas EUV/soft X-rays suffer from severe interstellar
absorption effects. Finally, HESS morphological studies of evovled PWN also
allow us to directly measure the effects of assymetric reverse shock
interactions due to SNR forward shock expansion into the inhomogeneous
interstellar medium.
