  We demonstrate area-enclosing atom interferometry based on a moving guide.
Light pulses along the free propagation direction of a magnetic guide are
applied to split and recombine the confined atomic matter-wave, while the atoms
are translated back and forth along a second direction in 50 ms. The
interferometer is estimated to resolve ten times the earth rotation rate per
interferometry cycle. We demonstrate a ``folded figure 8'' interfering
configuration for creating a compact, large-area atom gyroscope with
multiple-turn interfering paths.
