  We propose a new way to hide extra dimensions without invoking branes, based
on Lorentz-violating tensor fields with expectation values along the extra
directions. We investigate the case of a single vector ``aether'' field on a
compact circle. In such a background, interactions of other fields with the
aether can lead to modified dispersion relations, increasing the mass of the
Kaluza-Klein excitations. The mass scale characterizing each Kaluza-Klein tower
can be chosen independently for each species of scalar, fermion, or gauge
boson. No small-scale deviations from the inverse square law for gravity are
predicted, although light graviton modes may exist.
