We present X-ray imaging observations of several pulsars and their wind nebulae, comparing them to radio images where appropriate. While most pulsar wind nebulae have either a torus+jet morphology or a bow shock/tail morphology, in some cases it appears there is a hybrid morphology where on large scales there is a bow shape from their motion, and on smaller scales a torus+jet morphology which is tilted and offset with respect to the symmetry axis of the apparent bow shock. We present a simple model of the effects of an equatorially enhanced wind on a ram-pressure confined nebula. We discuss implications of this picture for birth sites and potentially related TeV sources....
