  We investigate a distortion in redshift-space which causes galaxies to appear
to lie in walls concentric about the observer, forming a rough bull's-eye
pattern. We simulate what an observer would see in a thin slice of
redshift-space, including a magnitude limit and constant slice angle. The
result is an enhanced ring of galaxies encircling the observer at a distance
roughly corresponding to the peak of the selection function. This ring is an
artificial enhancement of weak features in real-space. This may explain
visually prominent features such as the ``Great Wall'' and periodicity found in
deep narrow fields.
